I used to work on a lot of older muscle chevys (Nova, chevelle, camaro). I also raced the bracket series with my 70' nova. I tried a lot of different exhaust combinations. I was even dumb enough to think that open headers would not only sound cool but would make my car faster. The track proved that with no backpressure I lost up to five tenths in the quarter. I also had other competent "ricers" tell me that the reason their civic was faster than the other civics was because of the fact that the incompetent civic drivers would spend all their money and put a huge 3" exaust on top of a muffler designed to pull air through the system. I've seen this proven. Does a turbo really provide sufficient backpressure to where the exhaust doesn't matter? Again I have no experience with forced induction so please excuse me if I'm being ignorant.
