Talking What Exhaust Should I Go With ?
I Currently Have A Cobalt SS/SC 05

A Stage 2 Installed, Injen Intake, Short Header With 3" Exit & 3 " Dp With High Flow Cat, I'm Running On Stock Exhaust.

I Want To Get A Better Exhaust, I was looking around & I found the pacesetter exhaust for about 300 $ its a 2.5" catback i believe but from what people say it has an internal diameter of 2.25 " like the gmpp one .however it has better flow than stock.

Should I Go With That Or Should I Get A Bigger Exhaust ? I'm not trying to lose torque or Hp by going bigger than I need to

Any Suggestions Would Be Appreciated

From my research, a 3" is to big in my opinion for anything under a 2.7" pulley with full bolt-ons. A 3" is really only a necessity for a TVS or Turbo. With your set up, you would gain maybe 1-5hp over a 2.5" exhaust, if anything at all. You would also lose 15-25 lbs./ft. of torque with a 3" vs. a 2.5". My recommendation is to go with a 2.5" Stainless Steel exhaust system. Examples: Mandrelbentexhaustsystems.com, Magnaflow, SLP, CTi, etc.....

Hahn does sound really nice though imo.

I've been thinking about the SLP loud mouth. I also live in driving distance of SLP so I could go direct to them.
