hi guys, i have 91 600 kat, the original exhaust has finally started to blow ( not bad for a 20 year old part!) i wanna get rid of the twin exhaust and go for a 4 in 1. so what do you reccomend for a nice throaty sound but without the need for jetting. thanks you beautiful people you :bunny2

I believe any full exhaust you get it would be recommended to install a jet kit as well. As for a specific exhaust, I enjoyed my Vance an Hines Supersport before I swapped in a post engine.

Find an early 90s GSXR 750 header with a Yoshimura slip-on. That's what I had on my '95 750. Back the A/F screws out to 2.5 turns, stick with the stock intake and stock jetting.
