Best Sounding Exhaust for the ZR-1

[Z Factor]

Here is your chance to vote/comment on what you think is the best sounding exhaust.

:cheers:

[90ZR1]

I have the Corsa exhuast with vortech intake and am in love with the sound completely! Also the HP gains are nice too! Only drawback is its pricy.

[FU]

B&B with the resinator.
Your opinion may vary.

[1990 quasar blue]

I love my Flowmasters. They look close to stock, hardly resonate, sound great at WOT, and cost less than 500.00 brand new.

[We Gone]

Another vote for flowmasters...

[Fort94z]

I got to go with B&B with headers. Also have the x-pipe. Works well for me !:

[FU]

There are going to be quite a few different opinions on the question of what YOU think is the best sounding exhaust system. Everyone's opinion will be a bit different. Just like one of the above systems will sound totally different from one engine combination to another.

[Mikez40]

Not only is the B&B the best sounding, but also the best looking...of course that is MHO!

[rkreigh]

got a great deal on my B&B with x pipe. car picked up great power
and has a super agressive exh note.

the stroker needs this exh.

check out tbryne for the deal on this.

I was very happy with the service and price.

my 95 had a flowmaster which really sounded nice and was a bit
more mellow than the B&B but it's not SS

both sound great IMHO, the B&B is super rowdy. :cool:

[Jim Jones]

Mine had Corsas on it when I bought it, so having nothing to compare it with, I voted Corsa!! :cool:

[Dominicorvette]

Couldn't there be put sound clips on here so we know what each system sounds like? I think that would be really nice.

[Z Factor]

I agree.

Even if someone only had one of their own, post it and we I'll put them all into the OP.

:cheers:

[FU]

Marc Haibeck did some research on the stock 94-95 system :

[Dominicorvette]

What is OP? And maybe it'd be nice to put some zr-1 videos on here too? I know I would love that.

[Z Factor]

What is OP?

OP = Original Post

:cheers:

[bigd]

For Me- B&B with X pipe, breathing through Stainless Works headers.
Don

[Z Factor]

B&B is winning with 53%, but I wonder how much the resonance which I hear is bad with it takes away from the overall experience?

[WB9MCW]

fu2 how do u read the back psi report..it is blurry and will not control+ up in size??? :(

[FU]

fu2 how do u read the back psi report..it is blurry and will not control+ up in size??? :(

I saved it in Microsoft Photo Editor and enlarged and sharpened it.

The article basicly states that the best target for modification on the 93-95 exhaust system is the muffler. And that the cat's are a minor contributor to the back pressure , the resonator is the least restrictive.

[WB9MCW]

thnx 4 the synopsis fu2!!! :handshak:

[Patton]

Have any of you heard the power effects system??
It sounds sooooooo sweet, and crap is it mean! If you dont like resonance and cockpit noise than DO NOT get these... I for one love it, Hell my bose could have been broken for a year now and I wouldnt know. My music is live and has 8 intruments. I have heard the B&B as well, they are my second favorite, but Power effects takes it for me just brutally sweet big block sound, even at idle for crist sakes... I wonder what their "Side Effects" system sounds like?

[bobbyhi]

I also have the Power Effect exhaust system. Really love the sound at WOT..They can be toned down but who would want to!! Very quiet at highway speeds and in town they are mellow. My opinion only......:thumbsup:

[cuisinartvette]

I'd be interested to hear a sound clip of the newer B&B's.

[Aurora40]

I definitely wish more people were more sound-clipy! I love hearing that stuff. Does anyone here own the Callaway exhaust? It's 2.75" in diameter, and I'm hoping it on the lower end of the resonance spectrum, but that's based only on Callaway's reputation and the cost of it. I'd be interested to know if it suffers a resonance issue, or if it's not really that great at flowing, or whatever. It has piqued my interest the most as it seems a quality name, goes on a quality car, and hopefully is a quality product.

[Jeffvette]

5:30 mark is a good place to start as i pass him arund the 5:38/40 mark.

[Lowflight]

Stock Exhaust is the best....It Rocks:worship: :p

[cuisinartvette]

Jeff, now that sounds GOOD! Nice and raspy!

[Patton]

I also have the Power Effect exhaust system. Really love the sound at WOT..They can be toned down but who would want to!! Very quiet at highway speeds and in town they are mellow. My opinion only......

Say what? Mellow?? Well, the zr-1 i heard them on had headers and an x pipe with rt cats... maybe that is why we had to yell at eachother even at a stoplight. :mrgreen:

The B&B Bullet system sounds realllly nice on a C5... I would consider them for my Z if they only made a similar sounding system for it! I think the route 66 sounds like sloppy crap...

[91Mike]

Not real happy with the Borlas. Once the Jeals come in (3 weeks), I'll install B&Bs.

Mike

I installed a borla system on my 305ci 89 IROC, I could actually feel a negative performance effect during low rpms but felt like it revved faster and breathed much better at high rpms. I just wasnt satified so I tried the flowmaster system and wow,... Much, MUCH better performance throught the band, and better sound in my opinion. So yes I agree, borlas dissapointed me on my application too. :thumbsdo:

[WB9MCW]

the billy b's sound choice jeffery!!!:thumbsup:

[cvette]

Does anyone have a set of Desert Development exhaust laying around they want to get rid of? I've got the pipes but they have Dynomax mufflers on them. I would like to get ahold of a complete set.Charlie

[Jeffvette]

the billy b's sound choice jeffery!!!:thumbsup:


It's Corsa

[cuisinartvette]

Those Corsas? Looked like you had the sqarish tips. Anyway, sounds sweet! How is the interior resonance?

[WB9MCW]

shame on da mess...dog gone it ...fooled once again...well they sure sound good so it just goes to prove that b&b doesn't own the market for the bestest sound after all!!! now at thew dyno I have heard the bb's rule there but perhaps I could be wrong... :icon_scra

[Trizney]

Has anyone tried the magnaflow mufflers on their Z? I know most people upgrade the whole system, but a few just change out the mufflers. I have flowmasters on the Z, and the stainless magnaflows on my LT1. I was thinking of swapping them around just to see, but wanted to see if someone had already done this.

[Nick]

Those Corsas? Looked like you had the sqarish tips. Anyway, sounds sweet! How is the interior resonance?

There is no interior resonance with the Corsas. :thumbsup:

[A1990]

I like the sound and looks of the Corsa, but nothing even comes close to the B&B's!

The new ones are etched with the B&B logo which is awesome.

[LeoLily]

We've got a Borla exhaust - our BMW neighbor is Soooo jealous. :cheers: Wouldn't trade it for the world.

[sledutah]

Mine has the Power Effect on it. It sounds great WOT, it has a great sound at idle :mrgreen:

[zesstey1]

My 91 Z has Borla 3 inch pipe straight back from cats sounds great I made my own hangers to get square tips up in the openings where they should be and inside its not to loud until you mash the gas.

[NJZR1]

I loved the Borla mufflers on my LT1, loved that sound. Also, I don't know about anyone else, but I really don't like when you can see the mufflers hanging down from the side view of the car, like Magnaflows. The Borlas are rather flat,they seemed to tuck up underneath, and didn't show much.

I'd love to get a nice sound on the ZR1 eventually, stock OK for now.

BUT, I would like a high pitch at WOT, almost like a sportbike! ( I hear alot of C5's like that, wondering what system that is???)

I kind of enjoy the higher pitched sound, versus a low , throaty sound. (Guess I should own a Honda VTEC, huh?:sign10:)

[Patton]

Actually I agree with you on the sound. I like the higher F1-sounding engine note rather than a sloppy old big block effect. I don't know of any system that goes that route at all. the stock is as close as I've heard and its just to damn quiet. sounds great inside the cabin though.

[95ZR1#418]

Hands down, it's B&B w/ X-pipe & headers..... :wink:

[Aurora40]

To me, Corsa has that slightly high-pitched racing-motor sound. I'm not sure if it's what I want on my car, I like the mellower lower notes a little, but listen to some of the clips and videos Jeffvette has. His car sounds like a freaking race motor, it's great sounding.

Yours sounds great for stock, like I was saying!!

Gotta check out Jeffvette's vids. I love that higher pitched sounds, rather than the low muscle car sound, after all, I am a big F1 fan as, to, lets say Nascar!! (not that there's anything wrong with that!:-D)

[cuisinartvette]

This one makes me drool...Watch for Jeff about 5:40 into the vid. Wails as it accelerates and growls when it decelerates. This car chews with its mouth open and laughs about it.

http://www.pnwzr1.net/Jeff/Session1.wmv

[buddyboy]

My vote goes to Corsa. My wife could not stand the constant noise of the B&B and most of the others. Remember, a happy wife is a happy life.

1992 ZR-1 #330 White/white :wink:

[ShawnZR-1]

I was happy with my Corsa's before I put the headers on....now I'm absolutely THRILLED! I love the sound as it crests 5K RPM and it sounds wicked at 7K!!!

[Aurora40]

Jeff had/has a video of his car, but I always had a hell of a time playing it. It's like a 120MB .avi file that is only about 20 seconds long. My comp would stutter like mad. So I extracted the audio only. Hopefully he doesn't mind. It's his car on a road, and he basically just accelerates away from the camera:

http://members.aol.com/corvettezr11990/misc/Jeff_Vett_1.mpg

That track video mentioned earlier is cool too. It totally sounds like a race car is sharing the track with that C5 (6?).

My car is too quiet. I'll be addressing it eventually with some headers. Then I'll have to pick an exhaust. I like Corsa, but I don't know if it's the sound I want. I also think flashy tips don't look right on the 1990. I'd prefer something black, or maybe non-polished stainless. I do wonder if I could have Corsa powdercoat the tips or something. They do that for some of their marine parts, so they have the capability.

[John Boothby]

My 1990 has Flowmasters. They were on the car when I bought it. Just the other day I was cruising on the LV Strip and at a stop light a fella asked what kind of exhaust I had. He said he liked the sound. He had a C4, but not a ZR1. :cheers:

[WB9MCW]

I have Flowmasters on my 84 and I have to say they sound great for the wussy 205hp L98 motor!!! Thank god I put a 373 gear in her so she at least goes better on 0-60 times apx 5 to 5.5 sec now and allows me to waste 5slow blue oval stangs with auto trannies and my brothers now x 94 c4 lt-1 with auto...does great burnouts on the khumos as well!!!

[Aurora40]

I have Flowmasters on my 84 and I have to say they sound great for the ***** 205hp L98 motor!!!

The L98 was the next year. '84 was the Crossfire which I believe was the L83? (or L82?). :)

I had Flowmasters on my '87 L98, along with a front Y that removed the pre-cats. It was pretty loud but sounded great. However I can't get past the chambering in Flowmaster mufflers. I guess Corsas on the Aurora spoiled me, I like that you can see right down the whole thing, yet without a continuously perforated tube or the weight of packing.

[Mika73]

Headers + Random Tech cats + Corsa here.. :thumbsup: :notworthy

[WB9MCW]

thnx 4 the correction after much research I found in CF a c4 registry and it seems a lot o guys are confused what engine they have...some even think its an lt1! lol the majority say l83 so I think this must be right...check out the link and ull see a lot of guys thought like I that it was a l98 and multi port l98 for 1985 but I guess l83 is the crossfire!!! Heck one guy on p10 thought he had a lt4...lol talk abt ill-informed!!! I still say it is a wussy motor and that is why I did the mods I did till I got smart and just broke down and bought the KOTH... I still drive the 84 though when I wanna just go out and beat on a vette....better the 84 than the ZR-1!!! LOLOL and get this the 84 has only 52k miles vs the zr-1 with 60k miles...hence why I use the 84 as the true "BEATER" lol

That's what that was! It sounded SOO familiar but I couldn't pinpoint it. Of course, the good ol' V1!

I ain't that big. i was trying to hustle and get into the car before the camera stopped recording.

Yep, V1 is hardwired to the car. I use the other cord when I use other vehicles. I replaced the Ant a couple years ago. Fairly easy swap in the ZR-1 since you have the extra space in the back bumper.

[cuisinartvette]

Jeff, when you first started the car in your clip it sure sounded like you got some cam timing in there! Got any more of it idling?

[Jeffvette]

Stage 1 cams. I'll get some more clips.

B&B Hands down

[ZRWON]

Thought some of you might be interested in this video. Oblviously I love the B & B syetem too. It's a short video of my BEAST on some back Island roads. Poor quality camera work, but it'll at least give you a feel for the sound...has Watson Headers, 3 inch SS exhaust pioes and B & B triflows. No Cats or cross over pipes Click here to watch BEAST2-does-Whidbey-Island (http://media.putfile.com/BEAST2-does-Whidbey-Island)

[WB9MCW]

Nice vid Bill! It does give ua feel for the b&b's with the drone in the cockpit ect. The beast does sound great in that one romp where u wind her up! Looks like that DRM BW is working well still! How many miles on the motor now have you? I am presuming that u have the Beast back togather and cruizin again! And we now know u wear glasses and just what ur forehead looks like! Those in car vids are funny that way.

Sweet! The video seems to crap out less than halfway through for me, though (even saved it locally).

Is it sort of loud? It kind of seemed like it by the relative lack of any other noise, road noise, wind noise, all seemed very quiet compared to the engine note. It's always hard to tell in a recording, though, as I can turn my speakers up or down to make it loud or quiet. :)

THAT VIDEO WAS MADE ON MY VERY INEXPENSIVE CAMCORDER. MY SON DUG UP ONE HE MADE WITH HIS VERY GOOD UNIT...night and day difference in sound quality. It's only about 14 seconds long but the quality of sound inside the car more represents what it's really like. Son Dave nearly lost his camcorder when I floored BEAST going ~30 mph in 2nd gear.

[cwmoss]

When I bought my car, it had a Flowmaster system on it. Couldn't stand the resonance. The original system was back on in no time. I would be interested in another aftermarket system, but only after I had ridden in the car to see how it sounds from the inside.:thumbsdo:

Bryan, the entire Snake Skinner package Van Dorn did on BEAST 1 ('90 # 596 ZR1) was driven about 18K miles before it was totaled when the tree t-boned it in a Jacksonville tornado. All of the drive train and other Snake Skinner goodies were salvaged and used in Van Dorn's building of BEAST2 ('93 #211 ZR1 was used as a donor car).
Doug drove this one about 38K miles before he died and it was stolen from a consignment lot where Doug's widow had placed it for sale. It probably has close to 60K miles on the LT5 by now and it runs like I stole it. After the theft it was quickly recovered and again shipped to VanDorn to repair the LT5 motor that someone had started to dismantle. All of the parts were in the back of the car and repair was relatively minor but Jim VD "wanted it good as new" so he did a lot more to make it "perfect" for me to purchase.

[WB9MCW]

Yep that was a great story and very kewl 4 JVD to do it up 4 u right! I like the 2nd vid where someone says(presume your son while trying to hold onto his camcorder) "104" at the end! lolol. Really gives you an idea of just how fast your BW ZR-1 accelerates! Audio was a bit low though had to crank it but the mic/sound/audio was much better and the b&b's ring through!:thumbsup:

[ZRWON]

Yep that was a great story and very kewl 4 JVD to do it up 4 u right! :thumbsup:
Right you are about JVD being a class act. In '02 group from our Vette club went south for some sun. One,Stew, had serious problems with his carb & needed it repaired b/4 we headed back to the Pacific NW. I called JVD who spent his Saturday personally fixing Stew's car. Jim greeted Stew like a long lost buddy and his only customer. Stew was overwhelmed with Jim's hospitality and war stories, especially the Pirate racing things (see pic)
http://img.photobucket.com/albums/v346/zrwon/StewandJVD.jpg
Stew has not had any problems since Jim did his magic. He often tells folks the car still runs better than it did the day he drove it off the dealer's showroom floor in 1978! Sure wish Jim would get out of retirement and open a shop close to me.:worship:

[WB9MCW]

Bill I looked at your homepage 30 years of vetting! What a great Love affair...both the wife and the corvettes. Very cool! I have read bits and pieces of the Pirate Racing story and viewed the pic's from the Corvette museum and the placards ect. I was wondering if you knew of a complete story of the whole Zr-1 pirate racing. Were they part of Team ZR-1? Did you race with Team Zr-1? Perhaps if you felt so inclined you could start a thread in the personal racing section abt your adventures in racing vettes over the years! I have looked thru all the Team Zr-1 stuff and somewhere in there I think there are some great stories about racing Zr-1 and vettes in general. Perhaps others might join in and tell their stories! I think a lot of the original Zr-1 owners bought their Zr-1 to either collect as an investment, and there were others who bought the KOTH to race and these are the srories I and other 2nd gen Zr-1 guys would love to hear! jimo... tia... Bryan W :handshak: :cheers: :thumbsup:

[ZRWON]

Bryan, No, as far as I know, Pirate Racing, was never associated with Team ZR1. Perhaps JVD or some of the others can help clarify this. I did some Drag Racing around So Cal in the seventies and did some racing school sessions at Willow Springs, etc, but never anything in the league with the Pirate folks...just a guy on the sidelines cheering. I did sneak into the old Meadowdale Raceway in Carpentersville many times with friends before they dug up sections of the track to take away our private race track. I like your idea of a race section on the forum...wish someone would start it. Again I'd be on the sidelines watching and reading in marvel about our great toys. There were some excellent Pirate pictures published on the ZR1NET last month http://zr1netregistry.com/ZR1_racingpictures.htm I sent you a PM with much more ramblings.

YES Bill as z factor has pointed out there exists that section already. As u can see I just did a post there! This is a great time for u to tell me sum of the old C-ville race track stories!!! Start a new thread there called Race track stories from days gone by with the Meadowdale stories ( like anything u remember from that particular track and events and stories u might have) and we willl see if others join in!!! See I didnt even know u lived in this neck of the woods! They had shut the place down b4 I ever got to go there so I would luv to hear stories u have of the place!!!! :cheers:

Thanks
RAY:thumbsup:

Ray, the B&B is what I chose, but keep in mind it is very loud. I like the look & sound, but it takes some getting use to driving in traffic with the resonance at 1,800 RPM's. Other than that, you should love the system.

:cheers:

[BBBAD94ZR1]

Thanks you guys are great. My friend Rick as a 94 z with the bnb system on it.
I will check his out before I buy it. I want the car to sound as mean as it

Ray:thumbsup:

So Ray, which did you settle on?

[RPO_ZR1]

Not to cause controversy, but I think it's all in the 'ear' of the beholder.

I had the original OEMs on my L-83 for years. Well, in my youthful 'boy racer' exuberance, ... I gutted them and then they rattled windows and set off every car alarm within 2 full blocks!!! (I had a fun neighbor back then who was an old B-24 pilot... he would see me on the street, laugh and yell 'contact!'...)

As I got older, I eventually valued my hearing, (and at my wife's request), in '97, I switched the old L-83 to a custom Flowmaster-ZR-1 'race' system (by TPIS), which was actually quieter than my gutted exhaust with reduced backpressure, better top end, -but I still had to wear earplugs... (OUCH!)

So, when I bought my ZR-1 in Desert Palm Springs from the great Jim Van Dorn, it had a Borla system.

IMHO, compared to to the Flowmasters, Borlas have a 'sweet' harmonic sound, but I had long ago stowed away a virgin P.E system, (because Lingenfelter's Car and Driver SB-2, 427 beast had P.E.s.)

... When I asked JVD his prefs, he said "Power Effects", so I swapped the Z over to PE's, but this time decided to save my hearing if possible...

In my experiment, I put the Borla H-resonator at the front of the Power Effects Y-pipe. This produced an exotic exhaust note, cancelled out ALL interior resonance, and I got to keep my exhaust flow, + my ears no longer bleed.

I've been happy, the car sounds exotic and (best of all) I can finally carry on a quiet conversation at WOT, w/o yelling.

The car still sounds great... BEHIND the car.

Another upside is that your presence is not telegraphed to every freakin' 'Barney Fife' ticket trap in the county as you do the triple digit.

'Save the Wave!'

[ajaxajax2000]

I saved it in Microsoft Photo Editor and enlarged and sharpened it.

The article basicly states that the best target for modification on the 93-95 exhaust system is the muffler. And that the cat's are a minor contributor to the back pressure , the resonator is the least restrictive.

A couple of questions with ref to Marc Haibecks study and analysis:

1 Would you say these results apply to a 92 ZR-1 as well?

2 Do the quoted results mean that the best you can do is to replace the muffler(s) with open 3" tubes?

3 If so - does it require any other actions (air/fuel ratio etc)?

4 Or else - what is best to do (on the exhaust system) for maximum hp increase (and a sound worthy of the Beast)?

4 Or else - what is best to do (on the exhaust system) for maximum hp increase (and a sound worthy of the Beast)?

Peter :confused:
1) I wouldn't think so. The 90-92 resonator is considerably narrower than the 93+ one.

2) The resonator isn't 3" tubes and it wasn't a big restriction, so I'm not sure that's the only conclusion one could draw. In fact none of the system is 3".

3) On a stock car I think you wouldn't need to do anything if you didn't want to.

4) Best is highly subjective. I imagine there are several possibilities that will result in the same performance but a different look, sound, cost, etc.

[FU]

B&B with the resinator.
Your opinion may vary.

Took the B&B system off. Put the Corsa system back on. I love it. No bean can fart sound either. Must be the extra inch's.

[rkreigh]

the best sounding zr1 exh for me was my 95 (near stock) which had headers and the flowmaster. that being said, the B&B is better performing but a bit too agressive for most (including me at times)

I went with the B&B and x pipe and the random SS cats which do mellow it out a bit and man does it roar.

but the cheap and "not so high flow" flowmaster still had the deep tone without being too loud. car sounded great. I also had a desert development which was cool too.

try this. take a stock 2.5 exh, cut out the resonator, put in the X pipe and add some 2.5 magnaflow muffs. I think you will be pleased and it's not too expensive either.

for strokers, the B&B is pretty tough to beat for HP, use the X pipe, but be prepared, it's LOUD!!!

Good synopsis on the different systems.:thumbsup:

I've heard most of the systems with the exception of the DD, and from a price to sound ratio Flowmaster is hard to beat. I do however love my B&B with X-pipe and no cats, though I don't drive it for long periods of time.:mrgreen:

:cheers:

[jonszr1]

Has anyone tried using that X resonator from magnaflow. It would be very cool if one could have an xpipe that didn't make you eat asprin after an hr.:mrgreen:

[LeoLily]

I'd be interested to hear a sound clip of the newer B&B's.

Our B&Bs were installed a month ago. How do I create a sound clip? :confused:

[LeoLily]

Thanks you guys are great. My friend Rick as a 94 z with the bnb system on it.
I will check his out before I buy it. I want the car to sound as mean as it
looks.
Well thanks again.
Ray:thumbsup:

Ah - but the meanest sound is the Desert Development (if you can find one...) We had B&Bs put on as part of the rear-end repair until we can fix our Desert mufflers and put them back where they belong on our baby. :pray

My father-in-law had the DDs installed when our car was about 2 yrs old. One of his friends heard them "from at least 1/2 mile away" and had to buy a set himself. The resonation is high and you can "feel" it in the base of your skull at approx 2300 rpm BUT - they are the deepest, throatiest sound I have ever heard. The DDs are the reason my husband drooled over the ZR-1 for over 15 years (til we got if from the FIL a year ago August). :handshak:

I was at a car show this weekend and the vette behind me cranked up and it sounded unreal. I new it had to be a B&B but I asked anyway...it was. Ten minutes later I was ordeing a B&B with an X-pipe...can't wait for it to arrive! It was a toss up between the B&B and Corsa. I got the whole system brand new for $970 shipped to my house...is that good with the X pipe? :icon_scra

[blackjack]

i have the borla mufflers,with the resonator removed,replaced it with an x pipe,and i removed the infamous restriction inside the borla tubes...felt a difference in performance,and the sound is very reasonable;could even be louder,i wouldnt mind:) didnt notice any resonance...maybe because i had a"65 vette with a 396,and sidepipes...now thats resonance !!

I have watson headers x pipe in place of resonator w/ flowmasters. love the sound, also very easy to find the sweet spot of rumble or quiet depending on choosing 5th or 6th gear. I just wish they looked as good as the B&B's. I also have electric cut outs if I want to really raise hell!

I'm doing a custom setup involving Supertrapp mufflers. The B&B's were put on in the late 90's I think. Currently they have 4in Supertrapp disc only mufflers for tail pipes - you can run wide open (loud!) or add discs to mellow out the exhaust note. Also have the original squared/oval B&B tips. I can send you some pics via email if you like. I'll take $100 plus shipping for the mufflers.

[TeK_NoiR]

Does anybody have additional soundfiles or videos of Corsa,Power Effects or B&B ?

Surely the best would be a reality check, but I only know the real time sound of B&B - like it very much.

But Corsa could be also very interesting. As far as I heard it is a heavy tinny racing-like clang. B&B however seems to sound more V8 vibrant and Power Effects a middle thing of these two.

I didn't see your post Roger as many people know a vote updates the thread and don't always check.

As you might imagine the Borla is not stock. If you want a B&B system there are different vendors that carry it. Personally I got mine from T Byrne Motorsports when they had a group purchase going. There regular price is nothing special, but check with them to see when their next special will be.

My D&D had stock looking tips and smaller mufflers. The x pipe was two square tubes up front. System is loud and is as bad as the old B&B for resonance... It's also carbon steel...

[cuisinartvette]

The second gen B&B isnt anything like the first, its pretty quiet. Drove around a friends GS yesterday afternoon and I was shocked at how quiet it is inside, almsot no drone at all. If any it was very very slight low in the rpm range. Almost too quiet for me (from the outside at least), very tame and stockish sounding on the inside, just a little louder than stock.

To think I scored a new B&B system for $300 and gave it to a friend for his project, derrr!! THey are not crazy heavy like everyone says, either. Have it sitting in my closet lol.

The exhaust note is a very subjective thing with various opinions. With headers, no cats, a x-pipe and B&B exhaust, you will have one of the loudest sounding systems going. Some love it while others like a more refined sound. Your best bet is to listen to a few before buying because more than a few people have switched out their systems.

His 2nd favorite was a P51 ( Freestyle Prop Fixed Wing ).

The guy has every imaginable mode of transportation and he said the ZR1 was his favorite sound.

[Bob Eyres]

Watson headers, no cats, 3"B&B's (old style), Xpipe.

The most wicked sound is this system with mufflers off. I tried this after watching Mark Haibeck do it on his stock system at the drag strip. With 3" dumps it sounds like an insane shriek at 7K.
It actually drew a crowd after a run at the local strip,...WTF!!... Scared all the little ricers.

It is all subjective, of course, but my vote is for the headers/X-pipe/sans cats/3" duals into the Dynomax 17228s with NPP type vacuum exhaust flow valves. And, with Pete's cams and timing the LT5 has a slight chop in the otherwise stock idle which results in a delicious combination of deep notes with a menacing growl with the NPPs closed. When the gates open, people's heads turn when an LT5 is "speaking"!!

[1990 quasar blue]

I really have to make a sound clip of my headers random technology cats and flowmaster setup. I know the fbi is rolling there eyes due to the flowmasters lack of flow. And they're right. However, the car is fairly docile at idle and cruise, barely resonates, and at wot sounds simply wicked. I get compliments all the time on it. Also, the main draw for me was the close to stock looking tips.

Regardless of "Best Sounding Exhaust" being subjective, I like your thought about Marc's system. I am seriously thinking about doing this when I put the Dynomax mufflers on. :handshak:

http://i78.photobucket.com/albums/j86/hawaiizr1/DCP_0768-1_zpsb1591e95.jpg

I know this is an older thread, but I had Marc do this on WARP TEN in 2012 but then decided I wanted my spare back. Tony Davila did some manual cutouts right in front of the muffler so I decided I could do that also with the QTPs. Had Marc move them there and replace the spare carrier. They work great and we concluded that they probably provide just as much of a HP boost as the other version since they are so far back in the system and in any case when they are open the mufflers still can flow some exhaust. I am happy I did this, along with a hidden rocker switch under the carpet on the passenger side of the console.

And one note on the pictures supposedly about Marc's setup, the picture shown at the top is actually not what he has on his car but the setup he crafts and sells for his customers. In the mid 90s, long before they even had any electric cutouts, Marc sawed off his stock mufflers, welded up some bolt-on flanges and put Dyno Max mufflers on his car. What he does at the races is unbolt the mufflers and leave them off for the runs. Saves weight too but he said if he had to do it again he would go with cutouts.--Bob

[Crusin]

I personally like Corsa Exhaust for its design quality, as the straight through design gives less back pressure. As most know who have a ZR-1 the dual outlet tips look good but only one on each side is open and because of flange instead of having 2 1/2 opening there is only 2 1/4 opening on each side, thus more back pressure.

[32valvesftw]

After a while with my set up, which is long tube headers, no cats, x-pipe and Borlas mufflers I am thinking I want something a little quieter. Does anyone have experience with Flowmasters on the LT-5?

[ZWILD1]

My first 91 was done by my friend Jeff. He used the small tube Watson headers and the old 3 inch B&B and I thought it was the best sounding. With the 4.10 gears it had that resonance everyone complains about but I loved it cause I'm deaf and just love loud. It was a strong running car with no major engine mods.

So now the new 91 I have has the long tube headers , no cats, and the 2.5 Corsa that Mark installed when he did his engine package. It sounds really great to me. I was considering changing it out to a B&B but I like the older ones. I think the best thing is to not screw with what Mark did especially after seeing the dyno sheet.

[zr1eddy]

I have the Flowmaster exhaust that was designed for the ZR-1. I found the system on eBay, it was brand new without mufflers. I put Flowmaster Delta Flow Series 50 mufflers on. I think it sounds great, to top it off I put Flowmaster chromed angle exhaust tips on. If you can’t find the Flowmaster exhaust you could still go with the Delta Flow Series 50 mufflers.

It appears BB and Corsa are the two most used exhaust systems on ZR-1's. Wondering if Corsa has less drone than the BB? Thanks

[Bob Eyres]

B&B (old style) is very loud with lots of drone.
Corsa cancels much of the drone, and as a high pitched shriek at top end.
It’s really very subjective, a matter of personal taste. I have Watson’s, no cats, X pipe, and 3” B&B’s deep and nasty.

I think my modified LT1 stock exhaust system is great . I removed my power effects system so i could install exhaust cut outs. Brought a used LT1 exhaust system,removed resonator made my own " H " pipe and added 3 in cut outs
just before the mufflers. I did not want the spare carrier so cut outs are in a good location. Switch on center consul opens or closes the cut outs a little or a hole lot . I'am running Jeal Headers. I'll be at Tony D's this Oct the 20th.
here is a pic. of my system.

You did a great job on your exhaust, looks nice.
I think I will go with the Corsa less drone than BB Thanks

I replaced the mufflers with 16" of chambered pipe; now have the C2 side pipe kind of sound except louder.

I used ss tips and plain ss 3" pipe from the mid-pipe, and like you, I find it sounds loud and right!
Enjoy it!

After a while with my set up, which is long tube headers, no cats, x-pipe and Borlas mufflers I am thinking I want something a little quieter. Does anyone have experience with Flowmasters on the LT-5?Hi here is my exhaust sound I have made my own heads 2" primary into 3" exhaust with X pipe 50 series flow masters muffler if you look at my you tube channel you can see my first start up and can see the exhaust system

Corsa

[XfireZ51]

Too raspy.

[S.hafsmo]

I bought the Corsa due to its "raspyness", but I believe mine is broken, as it sounds mostly like my old setup with removed resonators and stock mufflers (without the drone, ofcourse).

Here's a clip of my new B&B Fusions at idle. Love these mufflers! Amazingly quiet at cruise. Wicked at WOT. And no drone under any conditions! B&B nailed this design. These are, BTW, custom made with no valves.

Watson headers and Corsa exhaust. Love the angry scream when I step on it. Nice deep rumble in lower rpm's.

Very nice indeed, Roy. Didn't know you had headers.
Does it still allow for a quiet cruise during the long hauls?

Are there cats on your setup?

I have headers and Corsa, without cats. It's quiet at cruise. Almost sounds stock. It's only loud at heavy throttle.

Its a repost,, but here's WOT outside the car.

Had borla when I bought it 12 yrs ago. Sounds good to me and yet relatively quiet on the hiway. Sounds better than my v-2 which has magnflows.

[XfireZ51]

I recently replaced my DynaMax Ultraflows w MagnaFlow mufflers. Both have the Z06 NPP valves installed on them similar to the B+B Fusion system. The Maggies produce a more mellow exhaust note at cruise. The Dyna had become very loud and raucous w a bad drone. And the Mags were fairly inexpensive and of better quality than the Dynas.

Would you happen to have a part number on those Magnaflows?? My stock mufflers are looking kinda rough.....

[XfireZ51]

I don?t recall exactly. Its either the 12288 or the 12198. Both are SS dual 2.5?outlet/3? center inlet. The 288 is 14in. length and the 198 is 18in. I believe I may have used the 288s.

Watson headers and Corsa exhaust makes this one sing.
