I have somewhat of a dilemma. I bought the bike new a couple weeks ago to ride as my desert/mountain trails weapon and I absolutely love it. But my main problem is that I need a USFS approved spark arrestor on it and since the bike came with the little shorty exhaust silencer which is all mechanical baffling versus being a strait through like most everything else so I cant get a promoto billet spark arrestor endcap. I called promoto and they told me that they are something like 4 months or so out from having these endcaps in production. I am not willing to wait that long and I want to ride (without getting a large ticket) now so it looks like I am forced to buy an aftermarket system to replace the stocker. My main question is since the 08 has different cams and port layout are the pipe manufacturers going to sell 08 specific pipes or are they just running any 06-07 pipe? Since I am going to be spending a sizable chunk of money on the pipe I want to make sure that it is going to be a good performer. So, if any of you have aftermarket pipes on your 08s could you please tell me what kind of pipe you have as well as what year it is for and how you like it compared to the stock system? Thanks everybody, any opinions are appreciated!!! BTW I am really looking at the full DrD systems since I know Drd pipes always seem to run great on Yamahas.
