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. It’s what your dirt bike deserves!

    FMF Gold Series Pipe, "Gnarly Torque"

    keith in MT

    Great clean power delivery

    Much better than the new ripple design thin wall ktm pipe. The stock pipe got bent on the first ride. The Gnarly is 18 gauge steel and much stronger. I has smooth power delivery in all rpm ranges. Works Great right off idle on steep technical switch backs. Does not hit hard and do Vigilant wheelies like some pipes.

  • FMF Power Core II Shorty Silencer

    FMF Power Core II Shorty Silencer

    Moses in CA

    A little damaged but works

    I give it a 4 star cause when I got the exhaust with the factory pipe, first I put the 2 together and they didn’t fit.The tube was bent so i wedged a something millimeter tool and hammered it so it will be round so that I can put the pipe together. After that it worked like any other fmf pipe would. BRAPPP!!! Increase in torque in the low end forsure. If your getting a lot of air out you gotta get a lot of air in. So installed a K&N filter as well. Sounds and feels much better than stock.
