Customer Reviews
“installed on a 2 stroke where all the previous packing had blown out or a mouse got it, installed this stuff and it works great! This is the first time I used loose fill instead of wrap but works great, just was not as easy to install as a wrap.” – Offroad Enthusiast
“This volcanic fiber muffler packing does exactly what it promises — it can handle extreme heat up to 1832°F (1000°C) without breaking down, even under tough racing conditions. After repacking my dirt bike’s muffler, the exhaust tone sounds deeper and cleaner, and the annoying drone is gone. One 500g bag was the perfect amount for my 19″ x 4″ muffler.However, be careful when handling it — this is fiberglass material, and it’s very itchy if it touches your skin! Definitely wear gloves and long sleeves while working with it. Once installed, though, it performs like a champ and lasts much longer than standard packing materials.Highly recommend for anyone who wants a durable, performance-ready muffler packing — just take the proper precautions during installation. ⭐⭐⭐⭐⭐” – Racing Fan

Frequently Asked Questions
Q: What size carburetor do I need for my 250cc 4-stroke dirt bike?

Q: How often should I repack my muffler?
A: Muffler packing typically needs replacement every 50-100 hours of riding, depending on conditions and riding style.
