first off i heard that i can mod on a stock exhaust from a camaro b/c it was the 2.25 that i want and it is dual but what i need to now is what year and the exact type also if the is any one that is selling srt parts for real and don't dissapear then hit me back i want alot of the srt parts but i want some upgrades too like a k&n air filter and cold air intake and then some kits like rocker kits cam kits new pistons and hope fully fully change out that rear sxt drum for discs that would be sweet.[&:]
