This won't work in any state that requires an emissions test. Q. Should you have a special exhaust?
A. No special exhaust is needed. You are required to remove your catalytic converter if you have one.
Umm.. Theres other ways of doing this. You dont need to run your car rich or remove your catalytic converter.
Hell, they dont even provide you w/ the ignition system (most important part) for this "flame thrower".
Its actually very simple to do. Just use some flammable compressed gas w/ backflow regulator and electronic valve w/ the right nozzle and a simple ignition system (could be off anything, find a junk lawn mower). Or you could use a gasoline w/ injector. Just install it all into the back of the tailpipe.
You also dont have to run your vehicle pig rich and slowwwwwwwwww
Not intended for the average joe shmoe who is uncomfortable w/ flammable gas or the clueless individual who doesnt want to use a backflow preventer
