Big Gun 09-23 Yamaha YFZ 450R Head Pipe

If you're looking to get more out of your 2009-2023 Yamaha YFZ 450R, this Big Gun EXO Series head pipe is a solid option. It's designed to work with the larger, more powerful sport ATV motors, giving you a noticeable boost in horsepower and torque. This isn't just about raw power, though; the unique hexagon-shaped aluminum muffler and stainless steel coned inlet work together to create a deeper, more tolerable exhaust tone while also helping to reduce heat.

The construction here is well-built, featuring a 304 stainless steel mid-pipe and head pipe that are TIG welded for strength. The large diameter, hexagon housing of the muffler allows for significantly more internal volume, which contributes to both the sound and the performance gains. You also get a removable screen-type spark arrestor included, and a black powder-coated stainless steel end tip for a clean look. The muffler itself is made from lightweight, brushed aluminum.

This handmade unit is built in the USA and is designed to be a direct fit for your YFZ 450R. Keep in mind that this part is not CARB approved and cannot be shipped to California.
