Looking for a bolt-on muffler for '03 GSXR 600, so probably any of the '01-05 600/750 or earlier 1000's should bolt-on. Going to be a shorty stunt muffler, so dented is probably preferred.

Ideally something like a TRS or RS3 or similar with riveted endplates so I can make a shorty and rivet/screw back together easily after I shorten.
