So I own a 2004 YZ450F. Have been using for a number of years in TX, and now I moved to NY. I need a spark arrestor here to ride anywhere. What is my cheapest option for meeting USFS compliance. I'm aware of the PMB spark arrestor, but that seems like a good amount of money to be throwing at my exhaust when I can likely get a used aftermarket exhaust for a few bucks more. I am more than happy with the amount of power this bike produces, so if I can pick up a cheap stock WR exhaust I'd be fine with it. That said, can a WR450 exhaust (or maybe even a WR250) be thrown onto my YZ450?

Another question would be what year exhausts would fit my bike? Could a yz426 exhaust fit? Pretty much whatever combo you can think of. Ideally I'd rather not mess with my carb jetts too.

Thanks guys!

Not sure if Lexx makes one for that year, but they are under $90 at Rocky Mountain MC. My buddy has one and likes it.

+1 for the lexx. You can get the whole silencer and mid pipe fpor $169. I think you have to get the screen seperate but still the cheapest choice out there. I have the Lexx for my 08, great exhaust and really opens the bike up with the MX tip.
