  • 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.

          Comments about Pro Circuit - 2-stroke Std 304 Stainless Silencer - Yamaha:

          The Pro Circuit 304 silencer is by far one of the best compliments to any 2-stroke motocross bike. The silencer bolts on in mere minutes and adds a great look to the bike. Stock washers and bolts must be used to install correctly, and it has a solid feel and hold. Upon starting my YZ250 with the 304 silencer newly installed, the bike roared to life with the sound of Chad Reed's 2005 supercross bike. The silencer sounds crisp and has a different tone than stock. Upon riding the bike, power is increased all throughout the spread, specifically in the top end of the motor. This product comes highly recommended.

            I replaced my spark arrestor with this pipe and there is a definite sound improvement.

            Only one bracket to attach to frame. Should have included a smaller bolt to replace OEM bolt that holds rear fender to the frame.

              This thing torques out of the corners. Great for almost any form of riding. Cheaper than the previous pipe I bought and this one is alot more durable. I hooked it up with the Pro Circuit Platinum 2 pipe. Man is it fast!!
