hey if any of you dump your two bros for a gibson or anything else, i might be interested in your twobros muffler. on my r1 crossbreed exhaust it's really (really) quiet and i'd like to set up a set of interchangable mufflers so i can have it loud or quiet. one alternative is to get another set of r1 mufflers and do the race baffle mod, but i have one twobros muffler and a pair of those would look pretty sharp.
