I have a Hepta Force Yoshi on my new Z. I have taken off the rear baffle but want more sound. Inside the link is this baffle with a tiny easy to break weld freeing the pipe. It should still have back pressure from the cat. Shall I wait for 600 service before removing?
Too long to wait! Took the pipes apart today and completely removed the inner baffles. Much more grunt and seems faster, particularly top end, not that I can go over about 6k revs yet. At least this mega bike now sounds a bit more like one!
