Frequently Asked Questions

A: Yes, the twin-stage core design is specifically engineered to reduce sound output while maintaining performance.

Q: Is this slip-on compatible with aftermarket headers?
A: It is designed to fit both stock headers and FMF PowerBomb headers.

Expert Pro-Tip: When installing a new slip-on muffler on your ATV, apply a thin bead of high-temp silicone sealant at the slip-fit joint between the header and midpipe to prevent exhaust leaks. Make sure to let the silicone cure completely before starting the engine to maintain optimal backpressure and prevent joint soot buildup.
