HMF Arctic Cat Swamp XL Series Exhaust

Don’t let the name fool you, the Swamp Series is more than a deep-mudding machine. It is the original in setting new standards for horse power, sound, and durability. What makes the Swamp Series so unique is the 5-inch diameter shell. This gives the exhaust more internal volume which, in turn, produces larger horse power gains. The large mechanical core directs and controls sound pulses to keep sound levels approximately 1-2 dB over stock. It’s shell is made of 304 stainless steel and the inlet is TIG-welded shut for a water tight seal.Swamp XL Series: The younger brother of the Swamp Series, the Swamp XL (extra loud) offers slightly more horse power than the standard Swamp Series. What makes this exhaust different is the non-restrictive core. Since there is nothing inside the core controlling sound pulses, the exhaust is louder than ever.
