5% hp increase for aftermarket cat back? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

That's what Borla is telling me. Seems pretty good. With the auto tranny I plan to get that puts me around 420 and no smog issues as it's cat back. Plus, Borla makes great sounding systems. My wife's Psassat sounds like a road rocket with it's Borla system. Any thoughts?

Borla all the way for me......

Too loud!

That's what Borla is telling me. I have a Borla full exhaust system on my wifes 99 Passat and it made a lot of difference. But, 5% for a cat back seems a little hign. Any thoughts?

I disagree. If that is too loud stick to stock. The Stock SS exhaust is very nice. This is not the 70's.

I will be getting Borla as well. 5% would be about 20 horsepower I guess we will have to wait and see when the dyno tests start to come in?

I think that's a lot for a CB, but maybe so with some tuning. I'm still planning on going with their CB, but it just seems like a lot. Considering 4th Gen. CBs were about 7-10 RWHP, may actually having dual exhaust will help that much more.

I know the vette is different but only got a 5HP bump from my Borla Sports aka STINGERS. 5HP is easily in the "noise" range of any dyno. So as far as I know anything could have caused that gain the day I re-dyno'd my 06.

GM gets 6 hp with the NPP on the vette.
