The Big Gun BIG EXO Stainless SXS Full System is constructed entirely from high-strength 304 stainless steel, featuring a stamped coned inlet and a hexagon-shaped large diameter housing designed to increase volume. The system includes a 304 stainless steel mid pipe and a rugged muffler, with the original aluminum base plate replaced by a TIG-welded stainless steel plate. A black powder coated stainless steel end tip completes the assembly, which is handmade in the USA.
Performance characteristics include significant horsepower and torque gains, supported by internal sound wave altering technology that produces a deeper but tolerable exhaust tone. The design incorporates TIG welded reinforced muffler brackets and includes a removable screen-type spark arrestor. This full system replaces the standard aluminum muffler with a stainless steel unit and features a stamped stainless badge, positioning it as the most durable option in the Big Gun lineup for withstanding brutal riding conditions.
