Like Borla kits say "F-Body 82-82 Single Cat" Does that mean V6's also? Anyone actully have a Borla on their 6?

 

the only diff between any of the V8 catbacks from each other is the way they connect to the cat...

from the I pipe back, they're all identical. as long as you can mate your cat (or "cat") to the I pipe, you're all set.

 

What is different about the way they connect to the cat?

 

GM used diffrent cats depending on the motor in the car... notice some cars are dual cat, some single... some have a long cat with a wide 4bolt flange, some used a totally diffrent one...

other then the cat itself, the I pipe location, rear hangers, ect... are all the same.

 

Some of the V8's used the exact same connection at the cat as the V6 cars, I know my 86 LG4 did, and 90-92 305 tbi and non g92 tpi cars did.

 

Only the '87 or '89 N10 optioned V8's had the dual cats, everyone else should be a single cat and everything SHOULD be exactly the same.

As far as I know, the option was available in either 87 or 89, and that was it. I know it was only for like 1 year or something. They tried to mount 2 cats side by side in the stock single cat area, and man, the passenger didn't have to worry about warming their feet up on a cold winter day.

 

Acutally the dual cats were from 89-92, however there were quite a few different single cat exhausts and the size of the intermediate pipe as well as the connection varied. Yes some were the same as the 2 bolt small cat (305 tbi, and 90-92 (possibly 89 ?) tpi non G92).

 

learn something new everyday...

 

F Bodys did use Dual Cats but for limited vehicles
Like IROC, ILE, Z28 rides,
when they were equipted with 350 engines.
The dual cats were exactly that, the factory manifolds going to dual cats, but then they were "merged" with a "Y" pipe to continue downstream using the single "I" pipe to a muffler out back.
Yes engine did gain performance.
Give Borla a call 877-462-6752
Pricey mufflers but you can decide if the price if worth your money.
PS don't dump on me for the design of exhaust. The 3rd gen is a very limited underbody exhaust optioned car. And one large "I" pipe can flow quite well...
Buy the headers from Pace Setter Exhaust instead and make some power....it's our restrictive exhaust manifolds & correcsponding "Y" pipe holding back the V6 engine power.

 

Wrong info again, dual cats werent limited to 350's

 

I believe quite strongly in my response.
Not saying to put up or that stuff, but I do strongly believe the dual cat set up was limited to just those rides I mentioned.
In the end, I gave ya the number for Borla so they can be asked.
And I'm very sure Borla can tell ya "exactly" which Camaros and/or Firebirds had the dual cat set ups....
The discusion ain't worth continuing.
AND IF ya knew why didn't ya supply correcting input?
I enjoy corrections anytime with accurate information.
Not a response without documentation.
That's bogus.

 

you can have dual cats on a 305 from the factory.


i donno the options or whatever, but ive just seen cars with them new....

 

I do not doubt that also.
I can strongly assume without doing major going thru old Hot Rods & such, it was reserved for the 350 engined cars.
Again I don't doubt that at all......that 305 SOME may have had the dual cat set ups.

 

You state that they were limited to 350's only, and only on certain cars, then I post the correct info, stating that they were on the G92 90-92 305's, you again post stating that you still uphold your original post, again implying that they were limited to 350's, which in fact they werent, any 90-92 G92 pkg 305 got the dual cats (now as far as limitations the 90-92's in order to get G92 on a 305 HAD to 1. be manual trans, and 2. be a hardtop).

It wasnt "reserved" for 350's, and you can leave your dusty box of magazines where its at.

 

Actually we're both correct.
I went to the Camaro White book
And the only detail I left out was the BC4 packaged cars.
I was correct only my calls of 350 limitations, too. If you ordered the 350 engine powered rides, you got dual cats.
BUT IF the car came with a STICK optioned 305 in the RPO optioned cars codes I mentioned, that car also would have dual cats. You were partially correct.
And I also said I don't doubt the 305 powered rides. And a 305 stick option in the IROC/Z28/1LE wasn't specified by yourself. I didn't feel like digging out this Camaro Bible I use often.

Now your final point is a partial correct, too.

IF the cars had checked off/called for the G92 performance package, yes, they did receive dual cats.
BUT you had to order the IROC-Z package with that G92, to get it!

One small, well GIANT hole in your theory, 91 and 92 there was no IROC available, sorry you're incorrect again.

90-92 G92 with a 305 got you dual cats, exactly as I stated it, no if's and's or but's.

 

Thanks for adding the correction.
Everyone appreciates it.

 

Im sure everyone appreciates the incorrect information also.

 

And everyone appreciates your reply.

 

As silly as this whole argument is, I really can't see a reason to take any action other than deleting jimp2001's reply.
