Catback Exhaust

Mods, feel free to move this if need be. I'm not sure where to put it. I also didn't find this through a brief search, so if a merge is needed, feel free.

Does the Catback Exhaust add-on do anything to the HP and/or, potentially, the mileage that you'd get?

Maybe a few HP, nothing that your butt dyno will notice, but it will sound meaner

I can't wait for a good exhaust sound video. Aftermarket or stock.

I've heard it could add as much as 15-20hp. And the sound will be significantly different than stock. I will wait though, I might go with another brand if it does not affect the warranty. It shouldn't tho!

I imagine the GMPP catback exhaust and shorty headers will add some HP. What the numbers are, who knows, but it sure beats throwing something on that quite possibly could void the warranty somehow.

It shouldn't affect the waranty. My friend has a balt ss w/ hahn exhaust and has never had an issue w/ his waranty.

Catbacks are mostly for sound.
In my experience with LSX vehicles (94 Z28, 99Z28, 05 GTO, 06 GTO), you usually see about 5-8hp from a catback exhaust on an otherwise stock car. It all depends on how restrictive the stock exhaust is.

More significant gains come with headers and high flow cats or race pipe alone with tuning.

Yeah, I've seen stated here maybe 5-7hp. But I'm getting it for the sound and because the mufflers won't show from the rear like the ugly, large stock ones.

Will The GMPP catback only be the mufflers and tailpipes with the larger tips?
Or will it be different pipes all the way up to the catalitic converter?

On an engine that's running 426Hp stock, you should definitely see more than 5-7HP. It's usually a percentage of the engine's original output power. That's why they can claim up to 30-40HP increases, because they place a restrictive exhaust on a Viper, test it, place in a less restrictive system, and test it again. Different gains on different vehicles. I am expecting the SS Camaro to see 15-20HP with a full catback system. I hope so, anyway.

The gains depend on how restrictive the stock is to begin with so it's not always the same percentage. If the the stock system is restrictive +15-20hp on a cat-back system could be seen, but if the stock system is less restrictive than the prvious F-bodies then maybe we will only see 7-10hp. It's too early to tell until someone can test the car.

Anyone that thinks they will be seeing 15-20hp on the Camaro by just replacing the stock cat-back is going to be really disappointed. The only way you'll be getting numbers at or over 20+ is with a full system (headers/x-pipe w/ high flow cats/cat-back).

From what i've heard from videos on the v6's exhaust i don't think i'd replace the exhaust, it already sounds like it has one on there. Man i love it.

Just rip out the stock exhaust and slap in a couple of big-ole fart cans. That'll give you at least another 85 HP....apiece!! Woohoo!!


Can you imagine what that would sound like??

I've wondered the same thing. From the sounds of most replies, the return on HP is minimal. But what about fuel economy? Would it go up, down, or not be affected?

Fuel economy would likely be up by a minimal amount if driven the same. But the exhaust note will beg for harder acceleration which hurts economy

Hell with that, I'm getting a GTR emblem to slap on. Now that's cool.

SS GTR



I am thinking of the catback, but not when I purchase the car. There will probably be aftermarkets for less.

I didnt know 94 Z28s were LSX vehicles...
guess ill have to go check under my hood to make sure ive still got an LTX car. lol











but yes, you are correct about the gains being complemented by a full exhaust system. everyone needs to remember that we have some bottlenecks in the exhaust system at the manifolds and the cats.


but i could see 7-13hp with a tune

*edit* I remember what I was talking about..... gutting the mufflers to make them louder on the cheap.

Does anyone know the price of the catback? Specifically the employee price? Also the headers? Any clue on that $$?

Thanks.

Catback is $850, so around $725 GMS. I think headers are $1050, though I'm not sure..

I notice this in a few videos so far about the exhaust sound between the V6 & V8. V8 having a much more deeper sound while the V6 sounds like there is a rattling sound every time you give gas. Will the Catback Exhaust fix this sound problem

its not something thats really a problem. a v-6 will not sound like a v-8. it just doesnt happen. you can make it sound close, but it wont sound the same
