Before last year it had been years since I've been on the trails. The way we used to do things, we used to cut silencers off, add a stinger, and cut it until the butt dyno told you it was good. Never used to have a problem.
Last years ticket was just for going around the guy that was supposed to be at the back of the pack... if that cost $200. I was guessing not having spark arrestors would cost about the same... but the noise could cost more???
Shit, I thought I was doing good with getting spark arrestors...
