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

EXO Series came about from a realization of the need for a bigger and better muffler that could handle the huge demands of the larger, more powerful sport ATV motors. The EXO Series is our ground-up approach at just that. A unique hexagon shaped aluminum muffler and stainless steel coned inlet allow for significantly more volume, delivering a louder but tolerable deep sound while also decreasing heat.

-   Internal sound wave altering technology for a deeper but tolerable exhaust tone
-   Stamped 304 stainless steel coned inlet for more volume
-   Hexagon shaped large diameter housing for more volume
-   Removable screen-type spark arrestor included
-   Black powder coated stainless steel end tip
-   TIG welded reinforced muffler bracket(s)
-   Significant horsepower and torque gains
-   Light weight brushed aluminum muffler
-   304 stainless steel mid pipe
-   Handmade in the USA
