With three removable inserts that change your ATV’s sound and power levels, HMF Racing’s Competition Series Silencer lets you dial in your machine’s performance perfectly. At the heart of the Competition’s powder coated, 6063 T6 aluminum alloy canister is the unique Trimax Core. This core has a triangular shape designed to extract every bit of horsepower and every pound foot of torque from specific areas of your power band. Using the different inserts, the core can be tuned for aggressive sound lowering, moderate sound lowering, and unmoderated sound. Each with the most power available for that decibel rating. Add in the USFS approved spark arrestor and the Competition Series Silencer is almost like getting multiple exhausts in one.

Specs:
