ORIGINAL: reckless929

Someone was telling me if you cut down the pipe it messes with the back pressure, and kills valves.......true??/
It will decrease the backpressure, not by much depending on how much you cut off and what you do with the packing and such. You can burn some valves if you don't tune the bike afterwards. Although I would imagine exhaust leaks at the head/header connection are far more likely to burn up your valves then a short exhaust
