Yoshimura RS-4 Exhaust System Honda CRF250L 

The work that went into developing the RS-4 muffler design paid big dividends in 2010 with Ryan Dungey winning the AMA 450 Supercross and Motocross Championship series as a rookie in the same year, and again in 2012 with the Yoshimura-backed GEICO Honda team winning both 250 Supercross Lites titles. That same R&D has been directed to developing the current generation RS-4 — a unique design that provides an unrivaled combination of power and a quiet exhaust note. The RS-4 features a Polyresonant duplex chamber, a two-staged stepped baffle and an innovative carbon cone end cap.

Features:

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Two-stage stepped baffle
  • Turn-out carbon fiber end-cap
  • Stainless steel headers

Note: Please check local laws before purchasing a Yoshimura Exhaust. Some modifications may be prohibited in some states.

Yoshimura RS-4 Exhaust System Honda CRF250L 2013-2015 4 5 1 1
Pretty Nice! I bought this exhaust for my Honda CRF250L, installed it in about an hour with the Yoshimura tail kit as well. Both look great and fit just fine, exhaust sounds awesome! Deeper tone and not super loud while cruising along. Throttle response is also much better now as expected. Only gripe I have is, it's already showing a little corrosion after it sat on a friends covered patio while it rained one night, so if you get one keep her covered! If that didn't happen it'd be perfect, but that's my fault entirely so I guess it IS perfect! Overall, awesome product, great sound, I'd recommend it to anyone looking for a bit more pep from their 250L. September 29, 2014
