SO I wanted to shorten my yosh slip on. I was told all you do is drill out the rivets cut it down, and re rivet. but I had 2 questions 1. it is a carbon exhaust, and Im afraid I will splinter the fiber yes no? 2. never taken one appart, but I assume there is a pipe inside how is it attached to the back cone? what do I do with it. just dont want to screw my exhaust.
