You have ever started a stampede with your exhaust.
I get a kick out of it every time it happens. I've only had my stack for about a month or two, but i've already started 5 different stampedes with it.
3 smaller ones and 2 FULL ALL-OUT stampedes. We live in the country and I drive 7-8 miles through farmland and horse stables before I hit a main road, si there are plenty of chances to. None of these have been on purpose at all, but I bet the farmers aren't going to like when I run all the fat of their cows!
Thought i'd share this...anyone else?
