I put a pic up in the files of my stock exhaust mod. Low buck pressure relief that seems to do the job and creates some conversation at the bike meets. Parts list: 1/2" copper pipe, 1/2 cap, brazing rod. Drill holes in the copper pipe to match the carbon blowout holes, brazed on with a jewlers torch. This may defeat the spark arrester so when your riding through fireworks factories put a 1/2 " cap over it and secure with a r-clip.
