dan moto jisu exhaust problems
So I recently started trying to customize my 03 honda cb919 and so far things are going well. I bought a jisu exhaust from dan moto and installed it but when I try to tighten the exhaust clamps on the stock pipes one of the clamps broke. (The other is tighter but not enough where I feel comfortable) I bought a new one and it seems to be doing the same thing, these are breaking before it gets tight on the stock pipe (loose enough where I can wiggle it on the pipe with just a little pressure). Am I doing something wrong or is there something wrong with these clamps? Should I be putting something in the pipes to help seal it better? I'm very new to this obviously. Any help would be greatly appreciated. This site has helped me out a ton already just from browsing.
