          Yoshimura RS-4 Slip-On Exhaust

          The Yoshimura RS-4 Slip-On exhaust has been put to the test and has proven its capabilities at the highest level of competition. In 2010 the RS-4 muffler helped Ryan Dungey claim the AMA 450 Supercross and Motocross championships in his rookie season. The Yoshimura-backed GEICO Honda team also took home both East and West Coast Supercross Lites titles in 2012 using the Yoshimura RS-4 exhaust.

          Utilizing the same R&D that helped bring success at the national level has resulted in a unique exhaust design that provides an unrivaled combination of power and quiet exhaust note. The Yoshimura RS-4 Pipe features an innovative carbon cone end cap, a two staged stepped baffle, and a polyresonant duplex chamber which acts as a muffler within a muffler to help save weight and centralize mass.

          Rated 5 out of 5 by from Quality product Good value for the price, sounds great, easy to install. Adding exhaust alone wont help however, you will have to chip the bike to get additional fuel to realize the performance
