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 ordered this exhaust for my kfx450r, it was at my door in 3 days, and took me about 10 minutes to install, super easy. Instantly after installing this pipe, I noticed the gain in bottom end power, it is definitely more snappy. I would recommend this exhaust to anyone. Keep in mind though, it is super loud.Read All Reviews

I spent a good week reviewing website reviews, watching You Tube videos, talking to dealers, etc. There are several options and manufacturers dealing with after market exhaust. The FMF Power Core 4 is absolutely AWESOME. The videos do not do justice to the sound this thing puts out! It went from sounding like a kitten to an angry lion in about 20 minutes of EASY installation. However, don't expect this to totally give you balls to the wall power. It did increase the performance somewhat and I am very pleased. The immediate change was just the awesome sound and rumble this thing puts out. My TTR is now as loud, or louder, than my brother's YZ! Highly recommended!Read All Reviews

Good exhaust for the price and nice to have another exhaust option on the market. Not the best sounding out there but does add a little noise with the quiet core removed, as well as a little low end power on my yz450f. Does have some rubbing issues on the tire and is very long which makes the bike look a little dated over the factory "shorty" silencer. Good for the money but if I could do it over I would probably save a little longer and go for an FMF.Read All Reviews
