How much horsepower difference is there between an open exhaust, a cherry bomb type muffler, and a stock muffler?
I've posted this before, the link you read can barely read is broken..... but it give some comparisons of dyno runs with only one variable changed at a time, however dyno runs change throughout the day



This is my car, passes sound at Lime Rock with one pipe capped, and a turn down...Remember atmospheric conditions affect sound... at a venue like Lime Rock, which is an old quarry, cloud cover, etc affects the way sound is bounced around... I have run there just with one outlet capped and passed sound, other days. No way!








On edit, my car has M&K header and a M&K Gen 1 RSR exhaust... which screams when uncorked
