I just got the Dr. D exhaust for my 2007 YZ450 and I love it. My only complaint is that it seems I have to take off the header to remove the oil filter cover. Is this really necessary? Anybody have any tips or suggestions? Thanks.

I always have to take the header pipe off, or slide it up to replace the oil filter. Its not that hard, i recommend getting some t-handle allen wrenches

I loosen only the nut and haul it up a little with a tire iron 'til the bolt clears.

for an exhaust setup that gets such awesome reviews (especially on our 450s) moving the header to change the oil filter seems like a decent trade-off in my opinion

Well, yes, but as I look at the header, it could so easily have been different. That's the thing that makes it a bit annoying to me.

Does anyone know the reason for the low-boy header, is it performance related or I assume it's designed to work with Dubach's radiator lowering kit?

If it is performance related you'd think they would could have angled the bend upward kind of like a stock CRF450R header

That's the deal, right there. On the CRF, the intent was simply to give it a longer exhaust system without having the muffler extend beyond the fender.

But DRD could have, and maybe still will, in the future, made the header differently. By moving the bend that is above the clutch housing forward one inch, and then rotating the outer half of the first U bend upward slightly to meet it, it would clear the front pump cover bolt. It only needs an 1/8".

yep loosen the header nut and allenhead bolt....lift the header slightly - top oil filter bolt should slide out
