Yoshimura RS-4 Slip-On Exhaust Yamaha WR250R / WR250X

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.

Yoshimura Race Series exhausts are designed with nothing but power in mind and are intended for closed course competition use only. Each Race Series exhaust is developed in accordance with noise compliance regulations imposed by most racing sanctioning bodies worldwide. Working in conjunction with factory race teams has allowed Yoshimura to develop a exhaust system that gives you an unparalleled competitive advantage.

Features:

  • Pentagonal-shaped sleeve
  • Polyresonant front muffler chamber which helps reduce noise
  • Two-stage stepped baffle
  • Turn-out carbon fiber end-cap
  • Yoshimura Race Series muffler 
  • Pre-installed spark arrestor included
  • 100% Made in the USA

Great Exhaust just a few down falls like any thing.
first things first they need to add to the instruction to remove the washer thing from the stock header before trying to slip on the exhaust it toke me a few minutes to find why it was not going on right in that time i manged to scratch the exhaust up a little witch is not a big deal as it is going on a off road bike, but shows how fragile it is as it was resting on a towel with metal screws, but after all this hardship just hearing the sound of the bike was well wroth it only thing is it is a little to load for the closed course riding i have to do in an area with NO Off road tracks. fit-met is a pain but i think there all like this, why bang for buck low because they do not offer a header for this exhaust and is also a little pries compared to others i looked at. overall great exhaust so far and would recommended to a friend ^^
