How much louder is the hmf utilty series compared to stock?? Does anybody have this on there foreman??? is jetting required???

 

well anything is going to be alot louder then stock if you go with the full system you will need to jet and I would also recommend getting a k&n...They should send a dynojet jet kit with the full system and hmf has a nice sound to them and on all of the quads I have heard with them are loud.

 

I have heard some and they are loud on the Foreman. I just put one on my 06 Rincon and OH MY GOD! its loud!

 

Thanks its a great deal, but not sure if i want a loud exhaust. Its got a uni filter now and thats it. Is there a good exhaust that is fairly priced, not too loud and wont have to rejet but still gives noticable gains?????? also how hard is the foreman to rejet??

 

hmf also has their quiet series which can be as low as about 96 db and jetting isn't that hard as long as you have an idea and if you have trouble then come on here and we can help.

Ok ready to buy the exhaust just wnted some more opinons. Its an 03 foreman with a uni filter. Looking for more power and nothing extremly loud. Any comparisons on the utillty vs: the QS1 HMF?? Hows the Penland?? Please some input!

 

the qs1 is quieter than the utility, but the utility gives you more power. probably a noticable difference, from what i've heard. I've been looking at the utility series pipes for my rancher eventually, and I ride in pretty remote area's, so a lout pipe isnt going to matter much to me, but then comes deer hunting in the fall and i dont want to scare all the wildlife into the next county going out to my deerstand. I wish I could try all the pipes out and then decide.

let me know what you think if you get any of these.

rejetting is necessary to avoid engine damage with just about every aftermarket pipe. talk to the customer support if you need to know jet sizes, they'll be able to put you in the ball park, then just check your spark plug color after a good ride.

 

Go with the utility series and just get a quiet core. With the core in their not that loud. I've ridden behind a 650 with and without and it was not bad at all. Its well worth the 20 bucks.
