HUH? YOU SAY SOMETHIN'?

You better think twice edramos.

Sounds great from outside. But resonance inside is beyond impressive.

In-cabin drone at low RPM's is HEAVY. It's got to be near the 16Hz range @ low RPM's.

Once I get the water out of the tank, I'll get dB readings for as-is, with cork sheeting in new roof headliner, with more cork sheeting under cargo carpet, and lastly, some type of resonator for 2 x 3" inlet + outlet.

Re: exhaust
 

I want to make a change but i don't want a mistake. The flowmaster system is good. there is no drone inside car at any speed. It is probably restrictive and if you want a meaner sound then a different system is required or a modification of the current system is in order. It is a crap shoot as to what to change on the current system. some say the resonator is the problem/ some say its the mufflers?? It would be horrible to cut up the system only to find out the modifications are less than desirable.

The flowmasters sound very good at wot but just not aggressive enough at idle or low speeds. I have seen that flowmaster makes the 44 series and the 40 and the 10. the ten is for race cars and its a one chamber muffler. it sounds ratty and too crude so its not a nice sound. the 40 and 44 series are two chamber desire and sound nice. Maybe that is the ticket??

Re: exhaust
 

Who here hasn't had at least 3 exhaust systems:p. For me it has been about 1 per year.

Re: exhaust
 

yeah on my other cars I have bought many exhaust systems. they can get quite pricey. I dont want to make that mistake plus I have no where to keep take off systems. I will wait a while and see what surfaces. I like the sound of the corsa's only with headers and no cats. Hopefully somebody wants to change to another system and sells their corsa.

I'm on my 3rd since February! ;)

Re: exhaust
 

Yeah Ed, I jacked around trying to find a less expensive option. I ended up with stock catted manifolds into straight pipes and it sounded AMAZING! Then I remembered I wanted headers and that would have been FAR too loud with those straight pipes. Like you, I didn't care much about drone at the time. I love the deep sound of B&B but wanted a custom system with an x-pipe and black tips, and the price they quoted me was ridiculous, even though I'm local. In the final analysis, I decided that since I was spending $1400 on a frigging catback (I have the black-tip Corsa...more expensive) I wanted to have it ALL, including no drone. I'm glad I stopped experimenting and spent the money on the only (IMHO) true best-of-both-worlds exhaust system. Hope this helps somewhat. Good luck!

Re: exhaust
 

yes it does help. If I want the sound of a headers/no cat Corsa, I need to buy one.

Re: exhaust
 

I don't at all regret this hardware - my motor is running MUCH cooler with it - there's NO doubt about it. If I could readily put OEM hardware back on and spec it for difference, I would.

But I do want to decrease interior drone here, without getting any restriction back - won't be east to do right...

Re: exhaust
 

I started out w 1 7/8" Watsons w 3G B+B. DRONE.
Went to headers w MagnaFlow 3" Cat-Back including resonator. Nice exhaust but more restrictive although it still made 399rwhp.
Now my final configuration is headers, SW Xpipe, DynoMax UltraFlows w
NPP Z06 tips and full open on/off switching. This is the exhaust I'm sticking with.

Re: exhaust
 

Hey Schrade, Daryll (GoldCylon) had (probably still has) a Corsa resonator for sale. It's 2.5" but a totally straight-through design. Might be a way to reduce your drone without adding restriction.
