FMF standard muffler packing for use on motorcycle, ATV and UTV. This packing is designed for 2-stroke mufflers. If you can't remember when your muffler packing was last replaced or if it has ever been replaced, it's probably time.
Premier series packing is made of fine interwoven fibers that have been blended to FMF's specifications for high heat resistance and sound absorption
Standard packing works great for M/X applications where maximum sound absorption isn't necessary
