i've heard that removing baffles can harm the exhaust valves.I did the stage one kit w/ the high flow air cleaner and the flash and put a set of"rush" slip-ons on a 06 SB W/ 1 and 3/4 inch baffles, but it is still so quiet. I removed the insulation from the baffles and just put the cones back in. Is this harmful to my engine?
