Big Gun 09-23 Yamaha YFZ 450R ECO Series Slip On Exhaust

The 304 stainless steel mid-pipe is a key part of this Big Gun ECO Series slip-on exhaust, designed to handle the heat and stress of your Yamaha YFZ 450R. This exhaust system is built to give you more power without costing a fortune. It’s a well-built system that aims to get the most out of your engine, offering a significant improvement in horsepower and torque over the stock setup.

You get a 6061 brushed aluminum muffler housing, which keeps the overall weight down compared to the original exhaust. It’s handmade in the USA to the same tough standards as other Big Gun exhausts, so even though it’s economically priced, it doesn’t compromise on performance or sound. A removable screen-type spark arrestor is included, which is important for trail riding and helps keep you compliant in many areas.

This slip-on is designed to fit your 2009-2023 Yamaha YFZ 450R, making it a straightforward way to upgrade your ATV. It’s considerably lighter than the stock muffler, which can make a noticeable difference in how your machine handles.
