Big Gun Exhaust 13-15503 EXO Series Full System

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.

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