I have an '04 636 with a full titanium akra exhaust system (header to pipe w/ carbon pipe). I have a K&N air filter and a power commander. When I ride for a while (about 20 min or so) in higher RPMs, my bike shoots flames out the pipe. It looks awesome, but I'm wondering if I'm losing horsepower as a result or if this can hurt my bike. Is my power commander adjusted right? any comments would be appreciated.
