FMF Racing Universal PowerCore 4 Slip-On Muffler

If you have an older model 4-stroke machine then the FMF Racing Universal 4-Stroke muffler might be for you. The straight through design of the spark arrestor canister and the performance flow stainless steel end cap ensures strength, durability and most importantly, track and trail proven unrestricted power.

The FMF PowerCore 4 features many of the design and engineering features of their top-of-the-line Factory 4.1 exhaust: Factory Forward engineering, durable fixed exhaust mount, sleek formed end caps and a removable spark arrestor screen. FMF didn't even cut corners on the materials list. Each muffler utilizes an aircraft grade aluminum sleeve for the canister and mount. High-strength stainless steel is used for the formed front and rear endcaps as well as the mandrel bent mid-pipe.
