Alright so I bought the WB Aluminum Pro and I honestly dont like it. It woke the bike up a little....but my lap times went down. This pipe rubbed my powerband in all the wrong places. And It came with that low header so I couldnt touch my oil filter. Honestly I like my stock pipe a little better because it is easier to ride with....
O and most of all....I know how to jet a 4 stroke, and this pi
pe wouldnt run for crap on my bike. Backfire pop backfire....
I honestly want to sell this pipe .....get a DR.D. Or a pipe that is cool that ALLOWS you to get to the oil filter..... so what you think I should strive to get the DR.D?

DRD was my first choice. and i can access the oil filter w/o removing or loosening the header.

Dr.D is a good pipe. I have a Yoshimura RS-2 titanium pro which I haven't had a chance to test due to 8" of snow on the ground. The reason I bought the yosh is it mimics the stock '07 power curve with just more everywhere including more torque. It sticks out the rear more than the Dr.D but it allows easy access to the oil filter.http://www.yoshimura...ull-system.aspx

I put a WB aluminum pro on my 07 yz450 and I like it alot. gave my bike way more power, way more. Granted I have an 07 and you have an 08 I would think that the WB aluminum pro would rip on your bike, especialy considering the stock 08 pipe. The 07 came with a corked up exhaust system the WB uncorked it for me. try adjusting your Pilot circuit, helped me alot with reducing the popping. You may need to rejet your bike. I was told that all you had to do on the 08 was replace the main jet with a 162, the WB installation recomendation for the 08.
