Its about time.

Alright, it's about time I get some growl from my 450r.

The pipes I have in mind are HMF Sport series, or the nMotion.

Any thoughts on either pipe are welcome, please give me some oppinions on which is better and maybe even some prices.

I LOVE the look of the nMotion but is it incredibly loud? Because it looks really small. And I LOVE the price of the HMF, but does it put out good numbers and does it have a nice sound?

i know a few people who have nmotion pipes. One loves his but it has a nmotion built motor. and yes they are loud. the other guy don't really care for the nmotion pipe cuz it is a stock motor and didn't make that much power. Hmf makes good power and can be used with a quiet core. you should also check out rossier pipes. They make awesome power and can be used with supertrapp quiet discs and they reach 98 decibels that way

let me tell u, the n motion puts out amazing power on a stock motor, im runnin one on my YFZ. sounds sick and looks great, deff. get one, much more diff then a hmf

If sound is an issue with you.. dont get the NMotion. It is LOUD! one of the loudest i have heard if not THE loudest but it definitly puts out the power. HMF is a great pipe that isnt too loud and it sounds great. I would love to have the NMotion pipe, but sometimes i think i would like to hear myself think while im riding or racing ... ya know? haha
Either one is great... just depends on noise and what you plan to be doing. Racing.. id go with NMotion. Recreational riding or woods riding i'd go with HMF.:macho

[st8jacket]

to me hmf's are obnoxouslly loud...

[450R_lover]

Haha... well then you should hear an NMotion.... they will ring your head when you are behind a quad with one. but they really get the exhaust out quick! Haha

[450raider]

all i can say is that my brother haas a hmf on his raptor 350 its like annoying loud... even the insert screen thing doesnt make much difference and that sucks cause i was wanting one but now ill look in those rossier ones myself.

hope this somewhat helps.

Anyone have some decible ratings on either of the two pipes?

[Mean250r]

the nmotion is like 105, you can always the the 12 inch, if your riding tracks and sound does not matter, get the n motion. awsome pipes

[Flyin-Low]

Hmmm, that is pretty loud... anyone have a some decible numbers for the HMF sport series?

Thanks Mean250r.

i dont know about other places but in 07 everyone that races NEATV has to follow the GNC national rule of 99db, so its not too long before everyone that races has to be under 99db, just something to think about if your gonna race

I heard that Jannsen is selling a pipe they call Outlaw that is not so loud but makes the same power as a dasa or rossier. 920-766-3411. 400 bucks shipped call em and ask about it
