I bought this about 2 months ago and I have absolutely loved it. It sounds amazing on my Raptor 350 compared to stock and gives it a much deeper rumble. Very easy to install, just had to remove 1 clamp, and 2 bolts and it went on with ease. You can feel the added power.

Sounds great. Nice loud deep roar. Bike revs faster. Make sure to follow Hmf jetting recommendations. I did and they were spot in.
I have a stock 2012 Brute Force 650 sra and looking to put one these on it is there any other mods that I need to do when I put this on without messing up something because it’s carborated and not fuel injected Help would be appreciated thanks
Excellent sounding slip on. Has a deeper tone than most and fit perfect on my 2017 yfz 450 and includes all the hardware for installation. Thinking im going to have to get a tuner for it to run perfect but power gains always have a price to pay.
Purchased as a Christmas gift for my son, he has a 2013 YFZ450. He has been riding it for a year now complete stock, and was ready to start tapping into the real power it has to offer. This Slip on was a perfect start for him. It was simple to install, only took about 20 minutes. It looks great compared to stock, cuts a little Weight, and sounds awesome. Not to loud and nice deep exhaust note. He said it definitely has more low end power, and can’t wait to take it to the dunes and really open it up. Would definitely recommend to anyone and plan on purchasing it for my quad now too.
It really gave my Honda Recon ES a much deeper tone to it would highly recommend
This exhaust really woke my 13 Raptor up! It’s like a whole different quad. Pretty easy install was nice as well.
Bought this for my 2013 Suzuki 400 LTz Immediately could fee the power difference and the sound of the exhaust is deeper
Needed a muffler for a custom build, Got great help finding the right exhaust from motosport. Was an easy install, deep sound not any louder than my old system, But did give me a little more speed Thanks

Question:Q: For someone who hasn’t been near an atv before, would the noise be loud enough to scare them? Because I want the noise to be as loud as possible on my 2008 Suzuki LTZ 400Question asked Over 8 months ago
Question answered by CodyGearheadUser's contributor status: Top 25Question answered Over 8 months agoAnswer: A: To get you a complete, accurate answer, I will need some more information. Is this person easily scared? Is it a small child we're scaring? Were they born with an irrational fear of ATV's that sound awesome? I can say that if whoever we're scaring fears exhaust that is 2-10dB higher than stock, then yes it will scare them as that is the decibel gain for the HMF slip-on. If you really want to up the fright factor, you could just take the muffler off entirely.

Question:Q: I have a 2007 400EX and i need to know how to tune my bike to work with this new muffler. Could you help?Question asked Over 9 months ago
Question answered by PaulUser's contributor status: Top 10Question answered Over 9 months agoAnswer: A: Whether for a sport bike, dirt bike, cruiser, or ATV, an after-market exhaust system or a slip-on muffler will improve the performance of your motorcycle, which is particularly important for the race track and competition.
The stock exhaust systems are designed to meet the emissions and noise-level restrictions set in place by most federal, state, and local authorities, and laws vary from state to state. It’s important that everyone check with local laws to understand what changes to your stock exhaust system are permitted.
Most after-market exhaust parts are lighter weight than the originals from the manufacturers. Most after-market exhaust parts allow the exhaust to flow more freely, and with reduced back pressure, and thereby improve performance. Performance improvements might be achieved with higher horse power and top end speed, or tuned for better low-end torque and quicker acceleration.
Allowing the exhaust to flow with less restriction usually demands adjusting and retuning of the fuel/air system, whether it is carbureted or fuel injected. In many cases, you might not know whether or not adjustment or retuning is needed until after you installed the new exhaust and taken it out for test-ride.
Some carburetors allow you to adjust the fuel/air ratio and the idle, but in some cases, changing the exhaust might require rejetting. Check out the simple guide to rejetting your carburetors: http://www.motosport.com/blog/a-simple-guide-to-jetting-your-carb

Question:Q: I have a 2005 Honda Rincon 650. Do I have to change the jets in the carburetor if I put HMF performance series on? If so’ please provide the part numbers I need to order..Question asked Over 12 months ago
Question answered by DaveGearheadUser's contributor status: Top 1Question answered Over 12 months agoAnswer: A: It may or may not need a jetting change. It will be based on your elevation above sea level and what other mods you have done to your ATV. If you do need to change the jets than I would suggest purchasing a jetting kit that is applicable to your ATV. If you need assistance finding one please give us a call.
