•bolts up perfect on a pedal sprint • buy some good baffle packing when you buy this. The stuff that comes with the pipe is a joke. •instead of using the rivets, I brazed some cap nuts to the inside of the baffle cap, and used some screws with loctite. • wipe it down with acetone, and spray it nice and thicc with some high temp clear coat. •performance gains are great on a stock a55 cylinder with proper jetting and air filter! Not too loud either.
