The TRC-D is the latest in Yoshimura's line up. This sli-on muffler resembles the popular TRC muffler, but with one very special feature: while the TRC-D features the same Tri-Oval shaped sleeve, Yoshimura took it a step further and created a Dual-Taper, Dual-Tip Carbon Endcap. The Dual-Taper exhaust manages sound better in both high flow and high power applications. The resultant sound output is music to the ears and lower lap times on the track! Tri-Oval-shaped stainless steel sleeve to maximize muffler volume while retaining superior ground clearance and a unique exhaust note. Offers a sleek silhouette to flow with the lines of the motorcycle. MIG-welded 20-gauge 304L polished stainless steel mid-pipe. Trick dual-outlet carbon fiber cone-shaped end cap with a removable low volume insert. Step-by-step directions and all necessary hardware included for an easy installation. Laser-etched heel guard. Minimizes unwanted weight for the performance-oriented rider. Weighs considerably less than the factory configuration because it eliminates the catalytic converter and dual mufflers.
