Yoshimura R77 Works 3/4 Race Slip-On Exhaust KTM RC390 / 390 Duke
Works Finish is not a coating, but a media blast finish using Yoshimura's own special recipe of ingredients. The result is an exhaust that, after it goes through a heat cycle on the motorcycle, takes on unique coloring that looks much like those works components Yoshimura's factory racers use.
The popular Yoshimura R77 Exhaust offers outstanding performance, thanks to being developed in the heat of competition. It features a trapezoidal design, which allows a large volume of packing material and in turn, delivers top performance. The R-77 muffler’s front cap is MIG-welded, while the end cap is riveted using high-end 304-L polished stainless steel rivets and bands.
This 3/4 system replaces your stock exhaust from the header back, eliminating your catalytic converter.
