Product Description

The Pro Circuit 304 Factory Sound Silencer is the premier choice for riders seeking a performance upgrade that delivers both power and reliability. Designed with a longer midsection than the aggressive R-304 Shorty, this silencer is specifically engineered to provide stronger mid-to-high-rpm performance, making it ideal for a wide variety of track conditions and riding styles.

Constructed with a durable 6061-T6 brushed aluminum housing and high-quality stainless steel tubing, the 304 Factory Sound is an excellent, high-performance replacement for your OEM silencer. It features double-walled mounting brackets for added durability and utilizes exclusive E-glass pillow packing for superior sound absorption. Designed with steel Allen-head screws, the unit is fully rebuildable, allowing you to easily maintain peak performance throughout the life of the pipe.

Frequently Asked Questions

Q: How often should I repack this silencer?
A: To maintain optimal power and sound levels, we recommend checking your packing every 15-20 hours of ride time. The exclusive E-glass pillow packing will degrade over time, which can lead to a loss of backpressure and performance.

Q: Is this silencer compatible with my stock pipe?
A: Yes, the 304 Factory Sound silencer is designed to be a bolt-on replacement for your OEM silencer, though it is engineered to provide better performance when paired with a Pro Circuit expansion chamber.

Expert Pro-Tip: When repacking, don't over-stuff the silencer. Packing should be snug but not compressed, as air pockets are necessary to properly dissipate sound waves. Also, ensure your mid-pipe joints are sealed with high-temp silicone to prevent exhaust leaks, which can cause erratic jetting and power loss.
