I have read on here how the newer headers on the WR's are not that great performance wise, and lots of ppl going to the YZ header instead.... How does the 04 stock header stack up? I got a bit of a ding in mine, and thinking of a "upgrade", but I would want something to help on the bottom end (not that it's really lacking there), and it already has a big mid/top end on it, so if I'm putting power somewhere I want it going down low, rather then up high. Would also like steel if possible, and looking hard at the FMF "FF" PowerBomb (Supposed to help bottom/mid), bit it is only available in Ti, compared to the "Moto" Powerbomb (Helps Top end, which is not what I want) which is in SS, but, they are both the same price. Right now, I'm leaning to the powerbomb Ti "FF" version. Bike already has a FMF Ti PowerCore , JD, and Hotcams, with all free mods. Any other suggestions out there you feel would be better?
