4-Stroke ATV Exhaust

Many aftermarket parts allow you to customize your quad, but nothing else has quite the same effect as a new ATV exhaust. The exhaust system helps control two vitally important aspects of any four wheeler: the noise level and the power output. By swapping out the silencer or even replacing the full exhaust system (including the mid-pipe or head-pipe), you can reach the sound and power you’re looking for.

If you’re looking for an ATV exhaust silencer, you can’t go wrong with Rocky Mountain ATV/MC. On this page, you’ll find silencers and exhaust header pipes for 4-stroke quads. And since the exhaust system is so vital to a quad, you’ll find major names here like FMF, Lexx, Pro Circuit, Yoshimura, HMF and others.

For four wheelers, riding the trail is just as important as tearing up the track – if not much more so. That’s why the silencers we choose to carry include USFS-approved spark arrestors, allowing you to enjoy riding in the woods both safely and legally.

If your ATV needs a whole new exhaust or just a silencer, this is the best place to pick one up. Enter your quad’s make, model and year above to see what we have available to fit your machine.

    Great exhaust Kx250f

    The megabomb was a great addition to the 4.1 muffler. I little deeper tone over stock and muffler. Added a little bottom end grunt and pull, and the whole system together really Gives the bike a better and smoother pull all the way through the power curve.

  • Lexx MXe Slip-On Silencer With Mid-Pipe

    Lexx MXe Slip-On Silencer With Mid-Pipe

    Richard in CA

    GOOD but PROBLEM::: What is up with the Fitment?? both the Mid Pipe and the Mid to Exhaust did not fit. I had to grind or Sand down connections and then had to use a rubber mallet to get the Mid pipe on and lots of sanding to get the Exhaust onto the mid pipe. Just Purchased this so can not rate durability! I will say performance seems good breaths well and woke up bike compared to stock bad shape restricting exhaust. The rest of the install was simple, and will see if there is any issue after time with the hangers. Also had to put the spacer on the outside of the clamp hanger and add a small spacer like 3 washers, other wise it was too loose around the exhaust body. I like the quick change for tuning or pulling the silencer and using just separately purchased spark arrestor. Looks good (I think)

    Added power to my bike

    I have the full system and as soon as I put it on I could tell a power difference. It really opened up the top end. The look of it makes it even better. I did however have a popping noise in the cold if I am letting the motor brake for me. Awesome pipe all around

    PAUL in CA

    Great Power

    I needed a spark arrestor and I purchased this one since the aluminum one was on back order and as always, sound is great and not too loud and provides excellent power throughout. I never rode the bike with the stock muffler so I cannot compare it but FMF always delivers power gains.
