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.

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.
