    Yamaha 304 Factory Sound Silencer:

    • This PC silencer popularized the Factory Sound movement in motocross exhaust technology. The aluminum body is riveted to the stainless-steel end cap on one end and screwed together on the opposite end for easy disassembly and repacking.
    • Features longer midsection than the R-304 Shorty for stronger mid to high RPM performance.
    • 6061 T-6 brushed aluminum housing.
    • FIM-approved, stainless steel tubing and end-cap.
    • Excellent replacement for the OEM silencer while offering big performance gains.
