I wouldn't buy from that site on principle.... they've been asked repeatedly to remove that picture of a Skyline, as the car is spitting flames not because of one of their kits, but because it's doing a dyno run and the guy who owns it is VERY :bad::bad::bad::bad:ed off about them stealing the pic of his car. Also, that pic of the porsche has been pinched from Gemballa, again it's spitting flames because of unburnt fuel in the exhaust, not a flamer kit....
Is Flame Throwing dangerous?
If you use common sense, follow the instructions and generally don't jack things up you and your vehicle should be fine. Always make sure no one is behind your vehicle and that there is nothing that can catch fire.
I love the disclaimer:

In the '50s, those things were popular on hotrods, and I can imagine with dual quads (twin, four-choke, downdraft carburettors), that there might be gas in the exhaust; how much unburned gas, or burnable anything, is likely to be in the exhaust gas of a MINI? In some highly polluted areas, the exhaust of a new car is cleaner than the air; if I strike a match, will the world catch on fire?
