which pipe is better

[Adam-400ex]

White bros E series or a hmf

[brian-250]

well, the welds crack on the Eseries where it hooks into the mid pipe, id go with the HMF.

[ethanp87]

HMF looks and sounds better

[reyes]

But wich one gives you more power??? its all about power!!

[blaster_rider68]

i think the HMF gives more power

[2muchquad]

it depends on what your looking for,which one will give you the power increase where you need it most?:D

[wheeltrax]

I have had both, altho not on the same machine. I would take the HMF.

[LazeR]

HMF hands down....i have the HMF Slip-on and i love it.....My friend had a 400ex with the full wb system and says my quad is way faster then his was!

[reyes]

I am interested on mid and top end power. HMF or w/b E??

[thrasher_ex]

hmf. i have w/b and friend with hmf. when we race with stock pipes i win but when we put our pipes on he wins. so yeah hmf gives more power

[MR.BIG]

I WOULD LOOK INTO CHM EXHAUSTS. THE WEBSITE IS CHMEXHAUSTS.COM
I JUST PUT ONE ON MY 45OR IN THE POWER IS INCREDIBLE AND ITS NOT EXTREMELY LOUD. FOR LOW END POWER I INSTALLED A POWER NOW KIT WHICH WORKS REALLY WELL.

not even comparible. ive had e-series and HMF on a 400ex and the HMF is MUCH better. the HMF sounds better, looks better, and gives more power.

[400Rider022]

HMF:macho

[reyes]

you say more power! were at bottom , mid or top? and have u tried both pipes? Is the HMF a new pipe? i notice it wasnt on the dirt wheels pipe shootout for the 400ex, So people cant really see the difference on paper . any body got personal experinces getting smoked by a 400ex with the HMF or something? Please contribute. Were i live everytime you go ride people want to drag race sometimes i win sometimes i loose. I want to enhace my 400 were it need it the most mid and top end perhaps i need not only exhaust but a good sproket combo,.

the white brothers pipe dont really add nothing but noise maybe 2 hp...they suck only the pro series adds power but they cost to much

are you talking to me? if so, YES ive tried both pipes(i believe i said that in my first post) i had a 400ex with a brand new e-series that i bought for it, got rid of that 400, then ended up gettin another one and went for a different pipe and bought an HMF. the reason dirtwheels dont have HMF in there is cuz dirtwheels is gay. and realistically, on 4-strokes pretty much every exhaust gives lower to mid power. no exhaust will actually give you more top end, thats all in your gearing. its just that the HMF gives MORE low and mid power! i can tell you just from riding it that i CAN feel a difference in this 400 compared to my last one. it just makes more power!

[reyes]

yes i was talking to you, Thanks for the reply am sold HMF it is,
