I have the Yamah GYTR pipe. With all of the DB level concerns, everywhere I would say. I want to replace or add a pipe downturn so the exhaust isn't firing straight back. Yamaha pipes are getting the reputation of the Toomey's on the banshees. They are ticket happy up here in the Northwest for raptors especially with this setup. I really frustrates me, so I'll do what I can since I love the sound of the pipe. I'm hoping Yamaha realizes these concerns and begins to manufacture extra tips for these pipes. Thought I'd throw it out there for all you raptor freaks.
