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. It’s what your dirt bike deserves!

This is what I put on my 501. It sounds gnarly but is too loud on long rides. I put quiet insert in it and now it's perfect! LOVE THIS MUFFLER. Perfect FMF fit and finish. I've been using FMF products for decades and they never disappoint. Takes 5 minutes to install.Read All Reviews

Used this on YZ250FX and 450FX. Broadens and extends power band. Provides nice exhaust note to boot. Durable and looks great!Read All Reviews

Fits exactly as it should. Unique mounting system. As you tighten the hose clamps they compress a softer metal mount against your pipe. Two problems I have: The mounts are scratching up the pipe as they get compressed. And, this mounting system does not lend itself to be removed and remounted a lot. If you take this shield off be sure to mark each of the mounts by which location on the pipe they came from. Otherwise they'll never mount exactly right again. Product does it's job with no fanfare. I don't notice it in place while riding. I DO notice not seeing fresh melt spots on my riding pants and inner leg of my boots. Excellent shield that looks pretty trick. (Can you tell how old I am now?) Down one star for this mounting system. They do what they're supposed to do (hold the shield on tight) but not doing us any favors in the process.Read All Reviews
