I have read post that claim that the Sideburner exhaust lowers horsepower because it does not have enough back-pressure. I have not run my bike on a dyno but was wondering if anyone has ever actually posted a dyno sheet with this pipe and with a stock pipe for comparison data? I do know that I was running stock filter housing with K&N's and stock exhaust and when I added the Sideburner and PC3 programmer I did not notice any loss of power but I have to admit that small horsepower loss would be hard to notice anyway.
