I was thinking about this thread as I started up my motorcycle last night. No cat converter on that one. The kid and I were playing with the puffs from the big single cylinder engine. I've been in races where there was a backup of riders on running bikes trying to get through a skinny obstacle, aka a bottlekneck, and we were sucking fumes big time.
100 times worse than a car, wow those cats sure work well.
