I'm riding up in Cloud Croft New Mexico in about a week, and I was wondering if there is any way I would be able to buy a spark arrestor for a 99 YZ400f...
Any help would be appreciated! :) :)

Check out promoto billet. They have a spark arrestor that replaces the riveted end cap of your silencer. You probably can buy it through thumpertalk store, or go to promoto billet website:


A lot cheaper than +$300 for an FMF Q.

If I were you I would save $20 and buy a Dr.D spark arrestor. He makes excellent products and it is the exact same thing as the ProMoto one except its $20 cheaper! Check out www.Dubachracing.com. That's what I'm going to buy as soon as I have the money for it.
