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.

Great slip on
Sounds great. Nice loud deep roar. Bike revs faster. Make sure to follow Hmf jetting recommendations. I did and they were spot in.

Sounds amazing
This is a great exhaust system. Sounds amazing looks better and I can feel the difference in the acceleration. You probably will have to change the jetting. Only took about 10 minutes to install, and they give you all the accessories needed.

Sounds amazing!
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.

Unleashed the beast
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.

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 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.
