Big Gun BIG EXO Aluminum ATV Head Pipes Motorcycle Headers - 13-24701

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.
