Description

The EVO R series exhaust system is designed to save weight, add noticeable performance gains (horsepower and torque), and improve the sound of the motorcycle. It features a hard anodized oval-shaped aluminum muffler, TIG welded reinforced muffler brackets, a 304 stainless steel mid pipe/head pipe, and a red powder-coated stainless steel end tip. It's lighter than the stock exhaust system, has a sleek design for maximum clearance, and includes a removable screen-type spark arrestor. It is handmade in the USA and comes with a 1-year limited manufacturer's warranty.
