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.

    Open up the power

    This FMF pipe is a lot lighter than the stock pipe and it lets the Husky breathe better for crisper response. Easy to install, fits great and looks great too!

    The power gain is real!

    Let me just start off by saying that I immediately noticed the power gains with this header. I paired this with my FMF PowerCore4 slip on exhaust, and I left black marks across the entrance of my dad's shop when slowly taking off. I now have to flip my tire around because the sharp edges on my knobs are gone, and with this exhaust, my tire spins a bunch. The only thing that you need to watch out for is keeping your pants off the "Bomb" part when riding. It turns blue and looks cool and stuff, but will melt your pants no problem. Just happened to me over the weekend.

    what I wished my raptor sounded liked when new

    Glad I finally bought an exhaust for my raptor and very pleased that it was this one. Sound is great and it slipped on with out difficulty. This is what I wish my raptor sounded like when I first bought her back in 08. I only have a k&n intake and this exhaust for now and everything is running fine. During my first ride in the dunes definitely felt as if everyone could hear me out there.. Haha
