Yoshimura RS-4 Exhaust System Honda CRF300L / Rally

The work that went into developing the Yoshimura RS4 Exhaust System 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 and mid-pipes
USFS Approved spark arrestor available separately
Made in the USA
