That depends on how you do it.
How were normal people affected by putting in carburetors in cars so they didn't spit out lead into the air?
Edit: My bad I meant catalytic converter not carborators (katalysatorer in Danish)

2. Carburetors aren't even on the exhaust side of an engine. Most cars don't have them any more (fuel injection), they mix air and fuel before it enters a cyclinder. You must be thinking of a catalytic converter, and that is still incorrect.
3. The only thing that stopped cars from spitting out lead was law and regulation in the US that banned tetraethyl lead additives.
The point is that the car industry moved on just fine.
