Re: Piping Size
piping is 2.5 untill it gets pinched down in the back to 2.25. A new catback will help a lot.

Re: Piping Size
ya ya thats what i thought.. well i was askin cause in a couple of weeks... im plannin on grabbin a 06" ss s/c.... but the thing is i heard about that catback problem and muffler, so now i was plannin on gettin chevy to upgrade my stock cat and muffler to a performance model... so that i could get full cover warrantly and boost it to around 220 hp offically stock... sound good or should i stick without the upgrade, have the engine somewhat loose power??? cause im plannin on doin shit after the warrantly.. so havin the engine runnin as well as possiable for lets say 4 years with the upgrade, would sound better.... i dunno what can anyone say about that?

Re: Piping Size
GM doesnt have an exhaust upgrade. Gm has no performance upgrades as of yet. They will after SEMA however.
As for upgrading your exhaust and intake, these mods will not hurt your car at all. Mostly what will hurt it is how you drive it or pumping too much boost without supporting upgrades like injectors and a tune or piggyback.
