FMF Racing Premier 2-Stroke Packing

What you get here is FMF Racing's Premier 2-Stroke Packing, designed specifically for their mufflers. This packing is made from fine, blended interwoven fiberglass fibers that FMF has put together to their own specs. It's built to handle high heat, cut down on noise, and give you the best performance and longest life out of your muffler.

This isn't just any fiberglass; it's a specific blend that FMF uses to make sure it holds up well under the heat your 2-stroke engine puts out. Good packing helps keep the sound down to a more manageable level while still letting your engine breathe and perform as it should. When it's time to repack your FMF muffler, this is the material to use to get it back to its intended performance and sound characteristics.
