You can do it with an auto trans just fine, put it in 2nd gear, turn off key, pump away...turn on key, BANG!
Turns out not only can you blow the muffler up (check) but you can actually blow a head gasket too (check).

NPP Easy to identify
All he has to do is look at the mufflers. If he doesn't have the vacuum actuators mounted on the top of the exhaust pipe coming out of the muffler cans just behind the exhaust tips then he doesn't have the NPP system.

I should get a vid, actually. Hmm, may do that one soon.
And what the heck is this 'carb' thing you guys keep talking about?? I thought that Atkinson guy eliminated those a few years ago with that diet of his.

Atkinson had it wrong, the more carbs the better. Three twos give you 6 barrels of carbs, two fours give you 8 barrels.

The other posts are about stopping back fire, but lots of Ferraris and Lamborghinis do this, and you could probably consider it a feature.

Is this something people do to their vettes ever? esp. z06
Obviously, backfire can be accomplished a few ways, some better than others.
