Can anyone tell me weather a white brothers e-series pipe would be better or an hmf pipe would be betterfor my 05 250ex?

well definatley get the hmf. it produces more power on other machines then the wb, its cheaper, its easy to take off the end cap if ever needed, and the wb brakes alot. so get the hmf no questions asked

My brother has an HMF on his 400ex, and it added quite a bit of power (slip on). I'm not really sure how much it will add to the 250, but I think since the head pipe will be replaced with the hmf, you should get some good power additions over the slip on WB since the stock headpipe on the 250 stinks

I personally like my Bill's pipe the best, it really opened it up.
