Yeah idk if its feels slower b/c is so dam loud and you expect to to be faster , maby its my immaginatiion lol

well it's a know fact that the louder it is the faster or more power you think you have....all you need to see is any ricer

told you ppl. that SLP **** is crap. its loss of power on a stock motor or near stock. it truely shouldnt be used a on near stock motor. to make up for it youll need some gears. i personally would of never went with that setup

I would never buy SLP stuff where were they when camaros were still being build..

Consider switching to Flowmasters. It sounds great and I dont have any power loss problems on my car.
