Big Gun 07-11 Yamaha WR 450F ECO Series Slip On Exhaust

The 6061 brushed aluminum muffler housing on this Big Gun ECO Series slip-on exhaust is a key part of its design, helping to keep weight down compared to the stock unit. This exhaust is built for riders who want more power from their 2007-2011 Yamaha WR 450F without spending a fortune. It's designed to give you a noticeable increase in horsepower and torque, making your ride feel more responsive.

Even though it's an economically priced option, Big Gun builds the ECO series to the same tough standards as their other exhausts. The mid-pipe is made from 304 stainless steel for good durability, and it comes with a black powder-coated stainless steel end tip. You also get a removable screen-type spark arrestor included, which is important for trail riding in many areas.

This slip-on is handmade in the USA and offers a significant weight savings over your original muffler. While it's not CARB approved and cannot ship to California, it's a solid choice for improving your WR 450F's performance and sound.
