Big Gun 03-06 Kawasaki KFX 400 ECO Series Slip On Exhaust

With this Big Gun ECO Series slip-on exhaust, you get a 6061 brushed aluminum muffler housing, a 304 stainless steel mid-pipe, and a black powder-coated stainless steel end tip. A removable screen-type spark arrestor is also included, making it ready for off-road use where required. This system is designed to give your 2003-2006 Kawasaki KFX 400 a noticeable boost in horsepower and torque without emptying your wallet.

The ECO series is built to the same tough standards as other Big Gun exhausts, focusing on delivering performance and a great sound at a more accessible price point. It's significantly lighter than the stock exhaust, which can make a difference in how your ATV handles. While it's economically priced, Big Gun doesn't cut corners on the materials or the handmade construction in the USA, ensuring you get a well-built part.

This slip-on exhaust is a solid option if you're looking to get more out of your KFX 400's engine. Keep in mind that this exhaust is not CARB approved and cannot be shipped to California.
