There is also a short round section of aluminum (4-5" long) inside the scat tube at the front baffle to prevent the scat from rattling around and hitting the exhaust. Second picture shows heat shield installed from antisplataero. The setup has been working wonderfully with no rubbing or chaffing. Be prepared though, the single heat muff on the -7 isn't sufficient below about 20F. I'll be looking to add a second sometime.
