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.

  • Polaris Yoshimura Performance Slip-On Exhaust

    Polaris Yoshimura Performance Slip-On Exhaust

    Hayden in Texas


    I was surprised how loud this system was. Wasn't sure what to expect. Sounds mean and people definitely take notice when I'm coming and going. I can still hear my music from the probox but I do have to trun it up a little more. No notice in power loss/gain but i have yet to install a power commander or fuel controller. Installation took about an hour and that's because i like to install without reading instructions. Good product for the price.

    Directions were simple, Loud and quite..

    This exhaust is perfect for the price, easy to install, very loud with out the quite core and had perfect tone. With quite core in was just a little bit louder than stock with the baffle in. As far as power goes I did gain some power.

    FMF Power Bomb Header Pipe

    Perfect fit, no clearance issues, no clamp needed between header and mid-pipe. Nice little bottom end boost with a Lexx slip-on.

    Great exhaust for the price

    Easy to set up and added enough power that I needed to install a beadlock to keep the rim from spinning the tube.
