This is the first HMF Performance Series designed to go “fender deep”. This bulletproof watertight design utilizes a 5” stainless steel canister for more sound absorbing volume and ultimate durability. It’s built for extreme conditions but suitable for all public areas. The Swamp Series creates more power and less sound than any other ATV exhaust on the planet. The five inch, stainless steel, TIG welded inlet and canister provide a water-tight seal for the serious utility ATV rider. More power. Less Noise.
