SOHC VTEC on mine. Still a lot of fun, but not the beast the DOHC is.
It's actually a D15B (1.5L) engine out of a junkyard in Japan -- the original D16Z6 got its cylinder walls scuffed up in an overheating incident (long story). Which actually brings up something relevant to this conversation -- I have never been called out on the incorrect engine block number during a smog check. I have all the US emissions equipment on it and no one's ever bothered to check.

If you're anything like me you'll immediately know if the catalytic converter is intact or not just by the exhaust smell -- un-catalyzed it's a heavier, more pungent smell, sometimes with hints of sweetness from unburned fuel. But I grew up when there were still a lot of non-catalyst vehicles around, so that scent is imprinted in my brain. (And the lead from the fuel is imprinted on my brain cells, probably.)
I don't think driving without a cat should hurt anything. You'll probably get a CEL in that case, and fuel economy may actually decrease a little. Contrary to what people sometimes think, modern engines are built with the backpressure of a cat in mind, and if it's not there the fuel maps aren't quite right.
