Here's my Gen 2 2013 Triumph Street Triple 675 with a SC Project S1 Exhaust with Baffle/DB Killer. The downpipes still have a catalytic converter installed in it.
Hi mate. No i didn't. Had a standard exhaust on the bike, then changed to GPR exhaust and then SC Project and I'll be honest I didn't feel any difference in performance whatsoever. The only difference I've noticed was the sound. I even road the bike on multiple track days and the bike always performed the same regardless of what exhaust I had on it
