does a catless exhaust have catalytic converters?
Best Answer: A catless exaust is an automotive exaust system that has no catalytic converter. If the system doesn't call for one, you shouldn't put one in. And if it requires one, you shouldn't take it off.Taking a catalytic converter off will affect the performance and life of the engine. catalytic converter or cat is a component in an exhaust system that essentially superheats the unburned gases to prevent them from exiting the car and making their way into the atmospere...strictly an emissions regulator.
