Big Gun 99-14 Honda TRX 400EX/X EVO R Series Head Pipe

This Big Gun EVO R Series head pipe is what you get when you order part number 09-1431. It's a direct replacement for your stock head pipe on 1999-2014 Honda TRX 400EX and TRX 400X models. This part is designed to help your ATV breathe better, leading to more power and a better sound than the original setup.

The engineers at Big Gun build these head pipes using precision-bent 304 stainless steel, and they're TIG welded for a solid connection. You'll notice it's a larger diameter than your stock pipe, which helps with exhaust flow. This improved flow translates to increased horsepower and torque gains, making your ATV feel more responsive. Plus, it's lighter than the stock unit, which can make a difference when you're out riding. Each one is handmade right here in the USA.

Keep in mind that this head pipe is not CARB approved, so it cannot be shipped to California. For other models, expect a noticeable improvement in performance and a deeper exhaust note.
