Please select make, model and year4-Stroke 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.

I just put the fmf power bomb header on along with fmf's power core 4 silencer and I am amazed with the the difference in power! Very very snappy throttle response and great low to mid range power and even in the top end it is great! Can hardly keep the front tires on the ground!! It sounds absolutely awesome too.Read All Reviews

Bought this for my wife's bike and it woke it up. Noticed better power throughout the range. It allowed her to pull the hills better. I was impressed with the noise level. Sounds great without making is loud. Would buy again anytime. Well worth the money for a mod to increase power.Read All Reviews

The quiet core cracked after a couple of rides, but it was replaced immediately with a new one that seems to be better quality. No issues with new core. I wish they would make a carbon fiber end cone for this pipe. Fits well, looks good, and provided a noticeable improvement in performance.Read All Reviews

Overall I'm pretty happy with this slip-on. It most definitely improves the sound by giving it a much louder and throatier sound compared to stock. I'm using it with the stock header, but I did remap the ECU after installation. I've got to say, I didn't feel THAT big a difference in power over stock. The bike definitely runs richer after the remap and it might pull a little longer overall after installing this slip-on, but it's not a night and day type thing. The only real negatives were the lack of any type of sealing gasket where the muffler slips on to the header pipe (had to use high temp gasket maker) and the fact that the can itself is not completely sealed where it is riveted together (i noticed some water being displaced from there upon start up after the first wash).Read All Reviews
