The M7 is what started HPS with Arctic Cat. This award-winning sled was a powerful reliable sled and at its time the lightest machine on the mountain. We made it even lighter and stronger!!! Adding +4 Horse Power and reducing -7.5 lbs, the HPS silencer for your M7 is a great choice. The New Platinum Lite Ceramic is a rich metallic finish rated for 2200 degrees and twice as durable as our previous polished coating. Coupled with our Double Walled Design that greatly decreases under the hood heat and reduces harmful engine harmonics. HPS has proven their designs with supplying two decades of lightweight and durable snowmobile silencers.
