Motorcycle 18-20 Yamaha XSR700 689 1. The result is a stainless steel exhaust that, after it goes through a heat cycle on the motorcycle, takes on a unique coloring that looks much like titanium. Motorcycle 15-17 Yamaha FZ-07 689 1.
Great sound; much better than the videos I listened to online. Easy to install after I fashioned a wooden wedge to spread the pipes. No intake or EFI mods yet. Exhaust by itself gives me lees low end power but more top end. I’m happy with the results but plan to do the intake and adjust fuel/air.
