It was the closest car to stock I could get. Baseline dynos were pretty consistent so we were able to dyno the exhaust on his car. The power gains were consistently from 28-34whp in the mid range. The only thing I can think of why I got the 40+hp was from the tune and the ram air. They might have made a difference with the stock and aftermarket exhaust.
