My friend has a HMF pipe of his 400ex and it gave it some serious horse power gains and i was wondering if it gave it more than the yoshi cause HMF isnt in the pipe shootout for dirtwheels

 

i duno, i had a hmf on my 400ex, and it made a hudge improvment, but its sold and long gone...[img]i/expressions/face-icon-small-sad.gif[/img]

 

We now have an HMF on a kfx400, BajaX and twin HMF's on a KFX700. The power gains are tremendous. The z400 that rides with us that had a Yoshi couldn't hold a candle to what the HMF did to that 400. WOW [img]i/expressions/face-icon-small-shocked.gif[/img]

There both good pipe but they have a little different power band, The HMF it a bottom to mid pipe and give great gains there and is real loud Where the Yoshi is more of a all around pipe that gives power everywhere and is quieter. Looks wise I thing the HMF looks better and you can get color matched can to match your bike.

I love my HMF but the neihbors hate it. All depends on the type of riding you do and where you need the power.

 

i want the bottom too mid cause i cant get into the top end much and i do 300ft drag racing and sound isnt a problem. and do any of yall have pictures of what the pipe looks like

 

HMF Raptor Full Exhaust

 

if you do drag racing top end is all you are in........
get a sparks dude........I raced a guy that "thought" he had the fastest raptor in town.....he had an hmf powder coated yellow.........although I put 3 lengths on him.....I think his silencer looks TONS better than mine....I really like the powder coated yellow!
(he had 101mm 11:1 je ported head....by the same guy that did mine and he has one of the larger web cams and springs and HMF full exhaust)
