Help 91 Random Tech or Magnaflow cats Part number

[GOLDCYLON]

Need a little help. I believe that I lost my drivers side cat this week. Sounds like a chock full O nuts around the resonator area. Figures as emissions is due on the 15th frankly the last 30 days of my life have been pure hell so it figures. Does anyone know the correct part numbers for the Magnaflows and the Random tech cats? I beleive the part numbers for the Magnaflows are 94006 for both sides but I am not sure. Im tired of dorking around with used cats so it maybe time to hang the set of JEALs. If anybody knows this off the top of thier heads PLMK and thanks GC

Gold One, if you do the switch to an AF cat and the Jeals you have been sitting on, I have 4 new stainless steel 3 inch reduction pipes that will make fitting to your exhaust much easier. May save extensive cutting and piecing. I have about $80 in the pieces but will take $40 plus cheap shipping for them. Best money you will ever spend. Makes headers and cats fit like factory.

Awesome Greg is this needed because the Jeals are a three inches on the down pipe side and I beleive my Corsa system is a 2.5? If so sold and thanks Greg as I said its been a tough month!!!! Also update!! The Car failed emissions and the coffecan full of nuts and bolts is getting louder I think the Drivers side cat ran out of it lives.

Does anybody here have a set of aftermarket cats they want to get rid of? Either model best price I have found yet is $65 each for the MFs.

Pretty much as you said. Stepping down from 3 inches to 2 1/2 inches. Makes life much easier. Also aids in the fit as two of the pipes are designed to clear stuff underneath. PP $50 shipped. PM me if you decide to go this route. :cheers:

daryl .,just a word of caution .if that cat has started to break up ,please be carefull as the cat material can work its way back into your motor with very bad results .just didnt want anything bad to happen to your motor . with you having a bad month didnt want to see one more thing go wrong .:cheers:

Thanks for that illustration. Thats what I was thinking it would look like. Ok update im going with the Jeals and I was able to pickup a set of Magnaflow cats 59959s for $137.36 Shipped. Let see if I get a performance pick up on this after this is done as well.... and pass emissions. Thanks for all the help. GC

[FU]

I like those transitions :thumbsup:

Are all 4 reduction pipes spoken for? I am looking for the best solution (i.e. fewest headaches) to hook up 2.5" Corsas to 3" headers/cats.

Sorry, George, GC picked them up.

[Gunny]

No problem. I was hoping that if you had 4 and GC only needed 2, that might be a possibility. Seeing the pix on this thread gives me an idea of what I need to do and having a pair of transitions should make the install a lot easier. Thanks.

[GOLDCYLON]

George if anythings left after the ZF.Doc is done I will drop you a line. I picked up the Cats at WWW.performancepeddler.com (http://www.performancepeddler.com) I did indeed get the pieces from Greg just to make sure the ZF.Doc had everything possible he would need.


Summit racing was $100 a piece which was considered a good deal. While doing the online ordering a pop up occured that said we will not be undersold if you dont like the price we give you can make us and offer and we will sell you our items at our lowest price possible that we cant put up on the web. Well that errored out so I called direct and he told me (Dave) the price was $68.68 a piece with free shipping. Wow a more than $30 discount each

Order ID: 79380

Sorry, George, GC picked them up.

And thanks for that Greg and PP sent and thanks again for shipping BEFORE payment received. Great little community here in the brotherhood :cheers:

Yeah at this point im pretty much parking it over at the ZFDoc's and awaiting parts. I agree I do not need any honeycomb material to end up in the motor at this point/ My Pop loaned me his spare Buick until this gets done. Bills is doing three sets of exhausts for my family. My pops LT4 96 CE will be getting DRM Shorty headers that we picked up used from Digital Diaster for $100 and they are coated!! These came with the motor package he had done to his LT4 now a 383 DRM 480 package. Digital Diaster has a really nice 96 GS but he wanted longtubes to go with his B&Bs and man does that car rumble the pavement. I know the shortys wont give my pop much more HP but I gotta believe he will pickup something as DRMs tend to know a little about performance. So we gotta believe they are better than stock and they mate to the stock LT4 cats which flow a whole lot better than the 91 ZR-1 Cats.

My sons LS1 Camaro with a set of direct fit OBX headers he bought himself and (He's paying for that install :dancing) Not me!! A full year in planning as my son works part time for Oreillys Auto (Formally Checker Auto)

And of course my install which came a little earlier than I wished but hey at least I had the headers already for the last year and a half. Jeffvette is betting I will be impressed and the port and polish job I had done to the top end 2 years ago will be fully realized. Bills going to be busy but he needs the work as well. At this point my car is so modded and a daily driver so its time to upgrade to a system which will allow me to replace the cats a little easier than what GM came up with in MY 90-91.

Well it sounded good on the 101 North Fri afternoon, yea that was me in my beater Sentra, Guess I know where I need to go to see some good mods being done

[tomtom72]

May I ask a Q? Sorry to hi-jack the thread GC...

The "transitions" in the picture are the s/s braided looking pipes?

If yes. Where do you find that stuff, at Jegs or summitt?

Sorry for the Q's. I'm a bit lost on this stuff. TIA!:cheers:

It was making the noise at that point I was hoping somebody wasnt trying to flag me down to tell me I was dragging my exhaust or something. It was good to see you Phil I was a little embrassed the girl was overdue a bath.

[GOLDCYLON]

so are you all going to the strip for family bragging rights when the cars are done . could be fun:thumbsup:


Not sure but a family photo when its all done is in order

[Sgreg]

I was wondering about those as well. I think they look great anybody know? :cool: No Hijack Tom I pmed the panzer to ask as well.

Braided hose is not the norm IMHO. Solid stainless is more common and D you are getting solid stainless.

Thanks for that Greg I was wondering if that was a heat or thermal barrier in a stainless lattice work that slipped over the piping?

[Jeffvette]

No, it's a flex fit fitting. It's a triple layer of braiding.

[GOLDCYLON]

And there we have it. Thanks Jeff hey did you get my PM on the bolts?

What you see in the pics I posted are:
Stainless Works headers w/ 3" OD collector outlets.
Magnaflow MPE-59959 7.75" length cats (with 1/2" cut from each side to further reduce length) w/ 3" ID slip on connections to Stainless Works header 3" OD collectors and retained by heavy duty SS seal clamps.
The Magnaflow cats have Stainless Works part # TT32.5 3" to 2 1/2" SS transition reducers (length cut to fit) welded to the discharge side (examples)http://www.stainlessworks.net/cart/images/tubing%20trans.jpg
which are welded to the 2 1/2" SS flex sections
which are then welded to the 2 1/2" Corsa system.
In my case I wanted flex sections right after the cats to help isolate vibration and reduce the bending forces transmitted to the headers and engine by the rather rigid construction of Corsa exhaust system. The SS flex sections are 2.5" ID x 4" long, slip-on weld type from Vibrant Performance part # 45544
http://vibrantperformance.com/catalog/index.php?cPath=1022_1035_1064_1113 (http://vibrantperformance.com/catalog/index.php?cPath=1022_1035_1064_1113)
(example)
http://vibrantperformance.com/catalog/images/45544_WEBL.jpg
These flexes are gas-tight construction with inner and outer braided SS liners to help protect the SS bellows. I would have preferred to use even longer flex sections and added SS V-band clamps to ease of assembly but Corsa pipe on the driver's side did not allow for enough length between the cat outlet and the first bend to fit all of these components in and at the time I did not want to get into heavily modifying the Corsa piping. As it turned out the flex sections were all that was needed to help make assembly and removal of the exhaust system via the collector clamp joints a snap. I have about 750 miles on the sytem since installed and so far no problems to report except for an even a more accute case of perma grin.

[tomtom72]

Thank you Mr. Jag for that easy to follow explaination!:worship:

I never thought about vibration isolation in our exhaust systems. Hummmm, I wonder if that contributes to the dreaded resonance issues???

Seriously, thank you for putting so much effort into the sharing your info!:thumbsup:

[RICKYRJ1]

If Phil did it, trust me it is done right. I have seen his set up in person and it does look trick.:thumbsup:

[jonszr1]

you can also find these woven connectors in the summit cat.pg 68. i think they may help in the resonance issue . i did for the first time take a look at the resonator sec. of my corsa what i found is straight through piping that has another bigger pipe welded around it . there are no perferations in it . so what i am thinking is to weld a gutted case around around a x pipe to see if that might cure the resonance problem i have with the x pipe system on my black car. it seems thats what the corsa did to a degree.

[GOLDCYLON]

Sorry, George, GC picked them up.


Many thanks to Greg for these pieces, Hopefully I get to pickup the car tonight and also see how the polished A-mold project came out.

The MF cats came in on Monday so was glad to get those. The Install of the Jeals according to the ZFdoc went well but I will get all the details on it hopefully tonight. I finally get to use Carters center wheel caps on the A-molds.

Then back to emissions next week. I guess the stock prom goes back in then no full power key for the test right? Need to decide to send my other chip back to Rippe or go the MH route

[jonszr1]

you might want to consider corey also for your prom needs .he has some neat tunes for our cars after porting .

[PhillipsLT5]

send it to marc

[GOLDCYLON]

send it to marc


Which one Phil the DRM chip or the Haibeck chip I have made an offer on? Daryll

[PhillipsLT5]

Buy a chip from Marc or have Marc reburn your DRM chip if possible to satisfy Marc's suggestions

[GOLDCYLON]

No problem. I was hoping that if you had 4 and GC only needed 2, that might be a possibility. Seeing the pix on this thread gives me an idea of what I need to do and having a pair of transitions should make the install a lot easier. Thanks.

George

George sent you a PM, I have three left out of the 4 left. We only needed one.

[GOLDCYLON]

Project update, headers are installed. As advertised with the JEALS no dipstick tube removal or movement was required and they fit up like stock. Will take pics but I dont pick up the car until Sunday. The drivers side cat was indeed done. It was internally broken away as one large chunk of substrate inside and was rounded almost into a catalyst ball inside as it mushroomed inside the cat. When you shook the cat in your hand it sounded like a softball was moving around inside. Yikes

So the new stainless bullet MF cats are up as well and the ZFDoc did a good job on the transition piping as well. Polished A-Molds with Carter's center Caps are on with the new rear BFG's. Looking forward to driving her home soon.GC

[-=Jeff=-]

Sorry to drag up an old post, but do you have Pics GC?

[Hammer]

GC, any better, I.e. straight on pics of those conections. I'd like to see a little more detail of them if possible.

Thanks

[GOLDCYLON]

No I dont have any and Im still working in LA, Currently at Morro Bay CA on a Dredge survey

[-=Jeff=-]

Are the the ends of the Magnaflow Cats 3" OD or 3" ID?

[Jagdpanzer]

Are the the ends of the Magnaflow Cats 3" OD or 3" ID?

3" ID

[Kb7tif]

Hope they work out.

[Hammer]

Ressurection.

Did you have the car tested? What was the outcome? DEQ is starting an emissions testing program here and I will need to have cats installed I'm pretty sure.

Thanks

[GOLDCYLON]

Yes I did and it failed miserably we use the IM-240 test out here not just a sniffer so a moron driving the car that cant shift can really tube the test. I Ended up registering the car at my house up in Flagstaff so problem resolved for now. I went with the MFs but I'm not sold the RTs will solve the problem. My engine has a lot of miles on it now so im sure that is part of the problem as well. At least I am running cats so I dont feel like a gross polluter

[tomtom72]

Just a fwiw on the low restriction/high performance cats.

I think part of the issue could be that the MF's or R/T's or any other of those type cat do not hold enough heat to work properly. They are made of a s/s alloy mostly and not just plain old steel. Stainless transfers heat too quickly vs aluminum/ steel alloy like the OEM cats.

I had an e-mail conversation with two different "coating" houses, and they both made the suggestion of coating the outside of low restriction/high performance cats with the same stuff that is used to coat the headers for thermal retention. Obviously, this conversation took place with respect to having headers and a smog legal exhaust system that would pass the tail pipe emissions limits.

Just thought I'd throw that out for your consideration.

I believe this is a strong possibility Tom. I deliberately reved the dog snot out of my car for about 30 mins to make sure she was good and hot and the numbers improved in the emissions test. Still did not pass. They are so close to the head pipes of the headers that I can?t believe they don?t get hot enough. But it?s a possibility

[Jeffvette]

You will have trouble passing the IM240 test with factory manifolds as well.

I just rolled a 94 through emissions up in Washington with the Magnaflow cats and had no issues. Another 368 as well. The cats are up to snuff, just the ZR-1 was never designed for the 240 test.

[Johnny5]

Demspey is installing my OBX Headers with CATS and he told me to buy Magnaflow 59959 cats as they will bolt up the easiest. They were $86 on ebay
