I bought an ex500 (Ninja 500) used that came with a Vance and Hines super-sport single exhaust. Anything over about 2500-rpm and the thing is ridiculously loud, even with earplugs and a full face helmet on (both of which I use anyhow).

Needless to say, I wonder if there's something simple I can put on the bike to quiet the exhaust short of buying and installing a full stock exhaust system. Do any of you know of a method or product that would do this?
