Removing emissions devices may well be illegal in John's state, but so is driving with the speedometer pegged, which owners sometimes mention on this List (Message #34198, for example). As long as he doesn't represent the car as being catalytic converter equipped, John should be OK (if his state does not require emissions testing). Many DeLoreans receive so little road time anyway that a de-emissioned copy will pose less environmental risk than a fully emissioned car driven frequently in rush hour traffic. Besides, John's current converter is useless. There is no way to replace its melted honeycomb. Bob's suggestion would at least allow him to continue to use the outer shell. Bob: a chisel won't be long enough to reach inside the converter. I'd recommend a 12"-18" screwdriver, or an old fashioned tire tool if a long screwdriver isn't available. The honeycomb is surrounded by wire mesh -- wrap it around whichever tool like spaghetti to pull out.

No cost. Looks stock!
