Big Gun Exhaust 13-2671 EXO Series Head Pipe

EXO Series came 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.

• Precision-bent TIG welded 304 stainless steel head pipe
• Larger diameter than stock head pipe
• Lighter than stock head pipe
• Increased horsepower and torque gains
• Handmade in the USA
• 1 Year Limited Manufacturers Warranty
