Dirt Bike Exhaust Systems

Aftermarket dirt bike exhaust systems are among the most popular upgrades that off-road enthusiasts seek. Why? A good exhaust system can add power throughout your bike’s RPM range easier than nearly any other mod. You can also tune it to your style of riding. Need to be stealthy for the hills? Want it wide open for the track? Rocky Mountain ATV/MC has you covered.

An exhaust system is a great way to really add some extra snap to your ride, but since it’s highly visible, it’s also one of the easiest ways to trick out your bike. After all, your friends can’t help but notice when a beefy new exhaust system is installed on your dirt bike! It doesn’t matter if you stick exclusively to the motocross track or the mountain trail, exhaust systems are important. That’s why at Rocky Mountain ATV/MC, we make sure to always stock an impressive selection at all times.

All you need to do is enter your bike’s make, model and year. We’ll display every exhaust pipe and silencer that fits your specific motorcycle. That way you know you’re getting a high quality product that has been carefully crafted to match your ride. (If you want to stick to original stock replacements, that’s great too. Check out our OEM parts.) If you’re just looking for a few good ways to customize your existing setup, take a look at our dirt bike exhaust accessories, where you’ll find a variety of options, including quiet cores, spark arrestors, aluminum pipe guards, silencer packing and more.

  • E Line Head Pipe Heat Shield

    Curt in CA

    Excellent protection, quality and style

    The first time this saves your $150 riding pants from melting onto the pipe, it'll pay for itself. In addition, it takes a tremendous amount of abuse so your pipe doesn't have to. I used one on my 2013 KTM 500 EXC in 2013 to great success, and it's still in good shape after a bunch of trips to Moab. I just put one on my 2020 KTM 350 EXC-F and it fits just perfectly.

  • FMF Q4 S/A Silencer

    Richard in BC

    Light with a bit more power, but fragile and unlike...

    The exhaust is lighter and offers a modest increases power over the stock XR650L exhaust and header. I bought both the header and exhaust. It was easy to assemble with high-temp silicon and no exhaust gaskets. After assembling, I noticed the header barely cleared the engine with about 1 mm clearance. Unlike the stock, there was over 2 feet distance between the exhaust frame mount and hanger in the rear, leaving the exhaust poorly supported. Within one year my exhaust broke at the weld. Dealing with FMF warranty was a frustrating waste of time; no discussion, one response and an automated phone system that took me in circles. In the end, they refused to honor their warranty because my exhaust had scratches and a dent in the aluminum. This exhaust may be lighter, but it is definitely not strong enough for a XR650L.
