also.....you would b suprized how big a difference an exhaust can make in a car. all motor cars HAVE TO BREATHE. if they dont then theyre getting robbed of hp. its all a combonation of things, the exhaust being one of them, that makes a motor perform at its best. so yes....exhaust does make that much of a diff.
