Make the lightest full size sport ATV ever even lighter and more powerful with the addition of a Two Brothers M-7 Slip-On Exhaust System. With the patented use of magnesium, aluminum and stainless steel, and hours of testing, Two Brothers has come up with an exhaust system to win races. Increased throttle response, more power throughout the powerband, and lighter weight all add up to a winning combination! New horizontal design! Bring the SOHC air cooled 350cc single to life with a new M-7 exhaust system. Add HP and torque while reducing weight and bringing the sound level to where it should be. Make the most powerful, sharpest handling Raptor ever, even better by adding one of the M-7 aluminum slip-on systems. Save more than 3 lbs. and add over 3 ft.lbs. of torque. Add over 3 ground ripping HP to an already potent 700cc Grizzly. POLISHED & BRUSHED ALUMINUM: Aluminum is a very lightweight and strong material used extensively in the aerospace, automotive, and of course, powersport industry. Aluminum is a wise choice due to its excellent strength to weight ratio, corrosion resistance and clean look. Lightweight, thin-wall .060 extruded 6061 aluminum alloy that is heat treated to a T-6 condition for increased strength, durability, hardness and finish hold is used. After the aluminum has been heat treated, it is cut to length and given either a polished or brushed satin finish. Ounce for ounce, aluminum is the best value of the M Series mufflers. As a rule the aluminum mufflers weigh about 8.3oz. more than Titanium or Carbon Fiber mufflers. V.A.L.E.™ ATTACHMENT SYSTEM: The V.A.L.E.™ system is the revolutionary and patent-pending method of attaching the muffler canisters to the exhaust tube without the use of springs or welding. The V.A.L.E. system allows the muffler assembly - exhaust tube and canister - to be positioned perfectly on the bike before all the mounting hardware is fully tightened. Once the canister and exhaust tubes are properly aligned, the V.A.L.E. assembly locks the muffler canister to the exhaust tube assuring a perfect, leak free fit. SPARK ARRESTOR: U.S. Forestry Service approved spark arrestors are included with all M-7 V.A.L.E.™ off-road slip-on exhaust systems. These tips mute the exhaust tone slightly with absolutely no loss of horsepower. Additionally, these tips prevent the introduction of foreign matter into the exhaust system FULL SYSTEMS: These systems completely replace the existing OEM exhaust system. This not only adds horsepower but also can drop significant weight from the bike. Two Brothers builds their header systems as a complete unit. The finished system flows better at the collectors which makes more power and does not vibrate on the bike.
