Big Gun 06-08 Honda CRF 450R EVO R Series Full System Exhaust

The EVO R series from Big Gun Exhaust offers a tried-and-true solution that significantly reduces weight, adds noticeable performance gains, and delivers a much-improved sound compared to stock. It features a hard-anodized oval-shaped aluminum muffler, TIG-welded reinforced muffler bracket(s), and a 304 stainless steel mid-pipe/head-pipe. The red powder-coated stainless steel end tip adds a touch of style. This exhaust system is lighter than the stock unit, providing huge horsepower and torque gains. Its sleek muffler design allows for maximum clearance. A removable screen-type spark arrestor is included. Each system is handmade in the USA and comes with a 1-year limited manufacturer's warranty against manufacturing defects. Proper tuning (jetting for carbureted, fuel controller for fuel-injected) is required to maintain the warranty and ensure optimal performance and engine longevity. Regular muffler repacking (every 15-20 hours) is also essential.
