Most the time I keep the smoke turned down on my comp because I get tired of getting flipped off.
this divided road only has room for one car so I pulled up next to him on the wrong side of the road, while turning my comp up to five which is set for fast throttle and BIG SMOKE. now mind you, my truck has 37" tires and a 4. 5" lift, my exhaust is at window level on a bug.
So I see a break in the traffic and jump it, he was starting to roll too, when I got through the intersection I looked in the mirror and he was stopped in the middle of the intersection getting honked at by the oncoming traffic, I think he had a visibility problem.
This is a regular for me, I routinely leave them in a big cloud of black smoke.
