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. It's even quieter with the optional forging kit that includes a stainless steel snorkel and heat shield but accepts an extension if needed for deep water or mud.
Features - CNC milled aluminum removable end cap - TIG welded inlet for uncompromising durability - Optional Snorkel kit includes Snorkel Spigot with a welded flange - 5" stainless steel, watertight canister.
HMF is currently experiencing unusually long lead times on all products due to increased demand and material availability. Due to this, expedited shipping is not available on these products at this time.
