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.

If you’re looking to add some extra power to your 4-stroke bike, look no further than the many options we have for 4-stroke exhaust systems. If you’re a die-hard 2-stroke fan, you’ll love our sections for 2-stroke pipes and 2-stroke silencers. It’s easy to find exactly what parts are compatible with your bike with our Parts Finder. 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.

At Rocky Mountain ATV/MC, we know dirt bike exhaust systems. That’s why we’ve chosen to carry the most popular brands, including Yoshimura, FMF, Pro Circuit, Lexx and more. When it comes to motorcycle exhausts, pipes, silencers and mufflers, we offer the best products at the lowest prices. So when you want to add some extra torque and bling, you know where to turn.

  • Pro Circuit T-4 S/A Complete Exhaust System

    Pro Circuit T-4 S/A Complete Exhaust System

    Nicholas in CA

    Better than OEM and cheaper.

    After the kids rattled the stock pipe on a TTR110 off the bike I bought this to replace it. Bolts on super easy and is made of much thicker tubing than the OEM pipe. Not much performance to be gained on such a small bike but it is solid and runs nice and quiet.

  • Enduro Engineering Spark Arrestor End Cap

    Enduro Engineering Spark Arrestor End Cap


    Great way to get your stock pipe spark arrested

    This is a great way to get your stock pipe spark arrested and not have to buy a complete silencer. Quality of materials is excellent, and I haven't noticed any power loss or change in sound. It took me a long time to install because I didn't have the right tools, but if you have them it should take about 30mins. You'll need a strong 3/16 bit (cobalt) and a powerful drill to drill out the rivets. After that the process is simple.

  • Flatland Racing Pipe Guard

    Flatland Racing Pipe Guard

    Joseph in WA

    Nice large aluminum pipe guard

    I wasn't able to buy this product from RMATVMC for my Yamaha YZ250X; saw it here and purchased directly from Flatland Racing. Judging by the pictures of the Tusk pipe guard, the Flatland is much beefier. Appears to be the best choice if you don't want a carbon fiber pipe guard. Hard to rate value because there is nothing really to compare it to. All other aluminum pipe guards I've seen appear to be too small. Less aluminum = lower price. The Flatland pipe guard wraps all the way up the sides of the pipe and covers more front to back, so it has more aluminum = costs more. The value will likely come from not having to buy a new pipe. The smaller pipe guards just don't look like they'd work very well- so yeah you might only pay $25 for something like the Tusk, but you'll probably end up needing to buy/fix a a pipe. All that being said, I haven't actually ridden with the Flatland pipe guard yet, so take my comments for whatever they're worth. Fit and installation are good/easy since it's just a few hose clamps, and the aluminum flexes a little. Bike: 2019 YZ250X with stock pipe

  • FMF Factory Fatty Pipe

    FMF Factory Fatty Pipe

    Bryce in ON

    Awesome pipe that looks great!

    I was skeptical at first how much I'd like this pipe, especially with the factory selection. When I had received the pipe I was thoroughly impressed with the build quality and it looked great. I did some reading, you definitely need to take care of the factory look to make it not look corroded. Overall the installation was a breeze and line up perfectly.
