I just got an SC400 and was wondering if I were to get Greddy exhaust.... would it make my car run like crap? I heard that it will screw with the back pressure and make it run worse because of the way it comes from the factory and how its supposed to just stay that way. Any pros out there know if its true?

 

it will not make your car run like crap. You may not see major power gains... just some increased sound and a better looking rear end- however, the back pressure that is eased up does not change the car in an ill manner- trust me, I have ran about 5 different exhaust and exhaust set ups on my SC4.

 

awesome thanks!
