I was watching monster garage awhile back. One thing that I found especially interesting was the final touch to a 100mph lawn mower/pimped out mustang-they added a modified burnz-o-matic propane torch to the exhaust somehow. The idea was; the propane would be ignited by the heat of the exhaust, thus sending a giant flame out of the tail pipe. Anyone know how this is done? I tried looking it up on the Internet but couldn’t find any info. That would be a great touch to my 95 940!
