When heading to the race track, everything counts, that’s why Yoshimura has developed their R-77 Full System Exhausts to deliver outstanding performance in the heat of competition. The R-77 features a trapezoidal design, which allows a large volume of packing material and in turn delivers top performance, a front cap that has been MIG-welded, and an end cap that has been riveted using high-end 304-L polished stainless steel rivets and bands. This potent power producer puts out an incredible exhaust note developed to produce an ear-pleasing sound that is nothing short of breathtaking while keeping the dB levels at an acceptable limit and have your heart revving for more!
