Yes, please do disable your catalytic converter. While you're at it, pour your used oil down the drain, leave the old antifreeze out for animals to drink, and just throw your old tires over the fence (set them on fire first to really give your neighbors a thrill). Old batteries make nice lawn ornaments. All sarcasm aside, the catalytic converter will reduce harmful emissions substantially while having only a trivial impact on performance. A display of callus disregard for emissions will only encourage more stringent environmental laws that restrict the use of classic automobiles, or in some cases even promote their destruction.

Increases exhaust sound somewhat.
