Frequently Asked Questions

Q: How often should I repack the R-304 silencer?
A: We recommend repacking your silencer every 15-20 hours of riding, depending on the severity of conditions. Keeping fresh packing inside is critical for maintaining peak power and keeping exhaust noise levels within legal limits.

Q: Will this fit my stock exhaust pipe?
A: Yes, the Pro Circuit R-304 is designed to be a direct bolt-on for the factory exhaust pipe, offering a simple way to improve your bike's power delivery.

Expert Pro-Tip: Don't wait until the bike sounds "hollow" or metallic to repack it. As the packing breaks down, it creates backpressure that can actually hurt your engine's performance and throttle response. Replacing the packing regularly ensures your bike pulls hard out of corners every time you hit the track.
