Moose Offroad Universal Muffler Core Sleeve - 15" / 19"

Moose Offroad Universal Muffler Core Sleeve (15" / 19") is a high‑temperature, dual‑length solution that protects the core tube and improves sound and performance consistency on many off‑road exhaust systems. The two‑layer stainless‑wire and stainless‑wool sleeve sits between the packing and the core, reducing direct fiber contact and extending the life of each repack.

This universal core‑sleeve set is offered in both 15" and 19" lengths, designed to fit muffler cores from about 1.75" to 2.125" outside diameter. The sleeve can be trimmed with scissors for mufflers shorter than the full length, making it suitable for a wide range of dirt bikes, ATVs, and UTVs. Used with glass or competition‑grade muffler packing, it helps maintain smoother, more predictable exhaust flow and quieter operation over time.

Moose Offroad (About)

Our story starts in the mid 1980’s in the shadow of the Rocky Mountains. The question in those days was how to prepare for an ever changing ride but for a core group of offroad riders it was a question of how, and out of their passion came a small offering of hard parts that would put Moose Offroad on the map. What they didn’t know was their desire to make the ride unforgettable would turn into a worldwide force of the finest collection of parts and gear for them and their machine.

In the early 1990’s, visionary Wayne Cornelius came along with distribution giant Parts Unlimited. Wayne knew Moose Offroad was good but he had a desire to make it great. His method to reach that goal was to consult the services of 8-time National Enduro Champion Dick Burleson. Utilizing Burleson’s experience the goal was to design gear that was comfortable to ride in all day rather than a 20 minute moto. That concept was launched in 1994 at the ISDE in Tulsa, Oklahoma, where a team of World-class riders emblazoned in new gear they served notice that Moose Racing has arrived on the scene.

As the 90’s continued, Moose Racing became the go to for hard parts but gear was the avenue to get brand recognition as it performed better than anything else in the market. This strategy blanketed races from the deserts in the west to the steamy woods of the GNCC with Moose Racing gear. It hasn’t been all offroad however, Moose Racing has been a staple of motocross as well. Moose Offroad is proud of its support for racers and riders at all levels from the bright lights of Supercross to the 8am races in the GNCC. Today, Moose Offroad continues the vision and strives to stay ahead of the pack, thirty plus years of blood, sweat, and gears has only made us more passionate to push on and keep evolving.
