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"

    Rich in AZ

    Beta Buyer Beware

    Firstly, I've always had good luck with FMF. Fit, finish and function are first rate. My go to when the stocker gets mashed. Given the above, the FMF Gnarly doesn't fit well on the 2020-21 Beta 300 RR. There are four points with minimal clearance. Between the pipe and the left side radiator around 5mm, there is less clearance between the left side frame below the exhaust port. There is less than1/2" clearance between the pipe and the right side of the radiator and it brushes up against the right side power valve cover. It looks like FMF just tweaked a 2015 KTM pipe and relocated the lower mounting tab.

  • Raven Swivel Exhaust Spring

    Mark in CA

    We like it tight

    They’re way stiffer than oem. Nice tight hold. Highly recommend an exhaust sprig tool to install and remove these.

    Pack your muffler meow.

    I cannot tell the difference between OEM factory flying machine packing and this brand. Works good.

  • FMF 4.1 4-Stroke Muffler Race Packing

    Nick in MI

    Great repacking

    Holy cow what a world of a different this stuff made! I pulled my fmf 4.1 apart and there was hardly any packing. I purchased this followed directions and had no problems what so ever! Don’t be the dude with a loud exhaust purchase yourself some new packing your friends and neighbors will thank you!

  • Polisport Armadillo 2-Stroke Pipe Guard

    Jake in OH

    Great for ding protection and small hits.

    I have 3 races on this pipe protector, as an advanced rider I rely on this to only protect my pipe for small impact and rocks thrown off my front tire. This is not a heavy duty pipe protector, so if you're bashing your pipe off rocks and trees. I would imagine this pipe gaud wouldn't protect on hard impacts. I do like how low clearance it is, and its easy on the eyes.
