i heard a while ago that the bostrom brothers started a company producing exhaust systems. they look pretty cool in pictures, anyone seen or heard them in person. click here to check it out (http://www.bozbros.com/)

My buddy's '06 ZX10 has the Moira full system (no muffler) that dumps in front of the rear tire. It is WAY loud :D (wear earplugs with your helmet), but sounds great! Prally the best thing is that you lose AT LEAST 10lbs.
