Re: Strange looking (long) header.....
It probably works, but boy, isn't it asking for trouble in boulder-strewn trail country !

I had to go up to the 185 m jet because of the powerbomb header
I am surprised. I didn't think it would make that much difference to the jetting. I haven't fitted the one I bought to my bike yet, so I'll let you know how it goes (ie. jetting wise.)
Could you feel much difference in the power delivery after you fitted it?
I only really bought it because it was cheap.... $Aus 150 (about $US80) for the whole system, one ride old.
I haven't decided what to do muffler-wise.
I have available:
1. Stock '08 WR450
2. Heavily modified '08 WR450
3. Stock '08 YZ450 "shorty"
4. Stock '09 YZ450 "long"
I might stick with option 2 for now. It is a little heavy but (I believe) as good, if not better performing than any aftermarket muffler at the moment.
