Big Gun 03-07 Kawasaki KLX 400R EVO R Series Slip On Exhaust

If you're looking to get more out of your 2003-2007 Kawasaki KLX 400R, this EVO R Series slip-on exhaust from Big Gun is a solid option. It's designed to give your bike a noticeable boost in performance and a much better sound than the stock setup.

This exhaust system is well-built with a sleek muffler that's shaped to give you maximum clearance, which is important when you're out on the trail. The muffler itself is made from hard-anodized aluminum and features a red powder-coated stainless steel end tip for a clean look. The mid-pipe is constructed from 304 stainless steel, and the muffler bracket is TIG welded for added strength. It's also lighter than the original exhaust, which can make a difference in how your bike handles.

Included with this exhaust is a removable screen-type spark arrestor, which is a good safety feature. Keep in mind that this exhaust is not CARB approved and cannot be shipped to California. It's handmade in the USA and comes with a 1-year limited manufacturer's warranty.
