To give your ATV a heavy punch and a deep bark, HMF Racing Sport Series Silencer was designed with ATVs in mind. HMF builds their Sport Series Silencers with a 6061 T6 circular canister and straight through baffle system for a boost in performance and the deeper exhaust note HMF has become known for. They’re also known for superior construction, and with the silencers TIG welded aluminum mounting bracket, stainless rivets, and 304 stainless mid pipe, this silencer is no exception. HMF seals the deal with their 2 piece billet end cap that fits their low sound output or spark arrestor inserts.

So when your ATV is in need of a silencer that can do it all without making compromises, pick up an HMF Racing Sport Series Silencer.
