Big Gun 08-10 Polaris OUTLAW 450 MXR EXO Aluminum Slip On Exhaust

The unique hexagon-shaped aluminum muffler housing on this Big Gun EXO Series slip-on exhaust is designed to handle the demands of larger, more powerful sport ATV motors. This isn't just about looks; the increased volume of the muffler housing allows for a deeper, more tolerable exhaust tone while also helping to reduce heat buildup. It’s a ground-up approach to creating a better performing exhaust system for your machine.

You'll notice a difference with the stamped 304 stainless steel coned inlet, which further contributes to the increased volume and improved flow. Inside, Big Gun uses internal sound wave altering technology to achieve that signature deep sound without being overly loud. This system is handmade in the USA, featuring TIG welded reinforced muffler brackets for solid mounting and a black powder coated stainless steel end tip for a clean finish. The brushed aluminum muffler itself is lightweight, and the mid-pipe is constructed from durable 304 stainless steel, all contributing to significant horsepower and torque gains.

This exhaust comes with a removable screen-type spark arrestor, which is important for trail riding in many areas. Please note that this exhaust is not CARB approved and cannot be shipped to California. For installation, you'll want to refer to the manufacturer's instructions, as this is a slip-on system designed to replace your stock muffler.
