i was wandering whats a better slip on for a warrior White brothers E series or an HMF pipe i like the HMFs but i heard white brothers was nice to so im not sure which to get any help wud be appreciated.

 

They are both good, but personally I like and use HMF.

 

On paper the White Brothers looks good as far as the power it is supposed to make. But it doesnt sound that great and doesnt look too good either. Id go with the HMF. Trust me, youll be glad you did later. After hearing my buddy's Warrior with his new HMF, I want one for mine! He also said it made a noticeable difference in power.

 

yea when i put my HMF on.. there was a definite power increase...

could especially tell in 3rd gear.. i ride at badlands and with my setup stock.. you needed a running start in 3rd gear to make it up hills and usually it would be bogging by the top..
that was with stock tires and a 13tooth front sprocket...

when i put the slipon on.. i could start at the bottom of the same hill and be freaking accelerating throguh 4th gear up the same hill..
mods were 14 tooth front, 20"kendaklaw XC's and about 10lbs more of rider..

it REALLY opens up the low end and middle.. and when u do aynthign to the airbox it opens it up even more.. i have a cut lid, and HMF, rejetted to 45 pilot, 1up on needle, 152.5 main and i am just flat out haulin in the snow..

 

I had the E Series, and their right it dosn't sound as good as the strait through mufflers. If your on a budget get the HMF, if not go for the Yoshimura, IMO it's probably the best pipe you can get.
