Spent some time in the woods this past weekend, and a friendly forest ranger reminded me that all vehicles must have either stock exhaust, or a spark arrestor. As my truck obviously does not have a stock exhaust, next time she sees it in the woods it needs to have a spark arrestor.

Anyone have experience with add-on spark arrestors? All I'm finding are little ones for motorcycles, or huge muffler/spark arrestor combos costing a bundle and more suited to a 400hp excavator tractor.

I need the Goldilocks spark arrestor. Needs to be USFS approved and fit 2.25" exhaust pipe. Bigger would be fine, I can make that work. Hopefully cheap too, as this'll get used maybe a couple weeks a year.

Ideas?
