Big Gun 09-10 Honda CRF 450R EVO R Series Full System Exhaust

Big Gun is known for building performance exhaust systems that help off-road riders get more out of their machines. This EVO R Series full system is designed specifically for the 2009-2010 Honda CRF 450R, offering a significant upgrade over the stock setup. It’s a tried-and-true system built to add noticeable horsepower and torque, while also improving the sound of your bike.

This exhaust system is handmade in the USA, with a head pipe and mid-pipe constructed from durable 304 stainless steel for good corrosion resistance. The muffler itself features a sleek, hard-anodized oval-shaped aluminum body that's designed to provide maximum clearance during aggressive riding. It also includes a red powder-coated stainless steel end tip for a touch of style. A removable screen-type spark arrestor is included, which is important for trail riding where required. The TIG welded reinforced muffler bracket ensures a solid connection.

Beyond the performance gains, this system is also lighter than the stock exhaust, which can make a difference in the overall handling and feel of your CRF 450R. It’s a well-built package designed to give you a substantial improvement in both power and sound. Please note that this exhaust is not CARB approved and cannot be shipped to California.
