FMF 4-Stroke Premier 4.1 Muffler Repack Kit

This high-performance kit is designed specifically for FMF's 4-stroke 4.1 systems, restoring them to factory-fresh specifications. Unlike traditional fiberglass matting, the Premier kit utilizes a unique blend of high-temperature resistant fibers capable of withstanding the intense heat and pressure generated by modern high-performance 4-strokes. Regular repacking not only maintains compliance with sound regulations but also optimizes backpressure, enhancing both horsepower and torque.

Features:

Designed specifically for FMF Factory 4.1 and PowerCore 4.1 exhaust systems
High-temp resistant packing material provides superior longevity over standard fiberglass
Helps maintain peak engine performance and optimal power delivery
Significantly reduces exhaust noise levels to meet track and trail requirements
Prevents excessive heat transfer to protect the muffler canister from discoloration or failure
Includes high-quality rivets and hardware for a complete, professional service
Proudly made in the USA
