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!

  • Husqvarna FMF Turbinecore 2.1 Silencer

    KEITH in MI

    Nice exhaust

    Needed a spark arrestor and didn't like the screen option . Typical top notch fmf quality. Figured if I'm gonna spend that much money on a slip on, I might as well spend a little more and get the husqvarna edition. Gave it 4 stars because I think it's over priced. No big performance gains or anything. Just makes me legal on the trail and looks nice. No screen to clean.

  • Fastway Spark Arrestor End Cap

    Steve in MI

    Don't waste the money on a 2 stroke

    I bought this to make my 2019 YZ450FX legal for the woods. I had every intention of purchasing the LEX spark arrestor, but with a back order date of nearly 6 months, it was to long for me to be willing to ride without one. The LEX spark arrestor costs roughly half of what this Fastway unit does, but it rivets on, rather than having removable bolts. The Fastway unit looks really nice, it fit perfectly, took about 10 minutes to install, and opened up the exhaust just a touch, which made it sound a little nicer. I prefer that the end cap is held on with bolts, rather than rivets. It makes the silencer that much more serviceable. It would be nice if the kit actually told you what drill bit to use for the self tapping screws, as the wrong size will either make the threads rip out, or it will be nearly impossible to tap the threads without ruining the bolts. As a former machinist, I had no issues, but I could see how it may be problematic for others. Several people have complained about having to drill and tap the holes, however I am glad that I had to do it. It just guarantees the holes are placed in the correct position.

  • FMF Gold Series Pipe, "Fatty Moto"

    Craig in CO

    Easy installation and that great FMF sound!

    Looks sweet and sounds sweeter! My son noticed an instant gain in horsepower. I suggest installing a VForce reed with the pipe, no sense in plugging up that new FMF with un-burned oil
