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.

    Tony in TX

    Yoshimura R77 for Bmw GS 1200

    Would have gave it 5 stars but the inner baffle was tac welded. Supposed to be removable by removing a screw. Sounds almost like stock but once I removed the baffle sounds great.

  • FMF Hex Q4 S/A Silencer

    FMF Hex Q4 S/A Silencer

    David in CA

    Great Product!

    This muffler works great! Bolted right up with ZERO fitment issues. Slightly louder than stock when hard on the gas but just as quiet as stock otherwise. Lighter than stock as well. It really woke the bike up performance-wise. The bike runs a lot cleaner and the throttle response is much better. More power too.
