I have an almost brand new two brothers carbon fiber slip on for an 06 GSXR600. May fit 750...not sure. Comes with quiet insert. Has an excellent deep exhaust note. Selling the slip on becuase I sold the bike awhile back and saved it incase i get another bike. I paid $430.00 for it new. Asking $330.00 obo plus shipping. You can PM me or text/call 765-635-4978
thanks
