I washed my bike last night, bugs...bugs...BUGS. Anyway I noticed the muffler looks like crap. Streaked and nasty. Anyone have any ideas on what I can use to clean/polish it up a bit? I know the header piper can be cleaned OR better yet coated as have found a local shop to coated it I just need to pull it off and drop it off (along with $100.00 and wait a week) The rest of the bike looks OK just the exhaust system always look like crap.
