Big Gun 04-09/12-13 Yamaha YFZ 450 EVO R Series Full System Exhaust

This is the Big Gun EVO R Series full system exhaust, designed for 2004-2009 and 2012-2013 Yamaha YFZ 450 models. If you're looking to get more out of your sport ATV, this exhaust system is built to help you save weight and unlock noticeable performance improvements over the stock setup. It's handmade in the USA, drawing on Big Gun's long history of building power-focused exhaust systems for off-road vehicles.

The EVO R series features a sleek muffler design that's shaped to give you maximum clearance, which is crucial when you're out on the trail or track. The muffler itself is made from hard-anodized oval-shaped aluminum, and it's capped off with a red powder-coated stainless steel end tip for a distinctive look. For performance, the system includes a 304 stainless steel mid-pipe and is TIG welded for strong, reinforced muffler brackets. You'll find this system is lighter than the stock exhaust, and it's engineered to deliver significant horsepower and torque gains. A removable screen-type spark arrestor is also included, which is important for trail riding and helps keep you compliant in many areas.

When installing this system, you'll want to refer to the manufacturer's instructions for the best results. The system comes with a 1-year limited manufacturer's warranty. Please note that this exhaust is not CARB approved and cannot be shipped to California.
