The definition hits the high points. Certification is voluntary, not imposed by government. It is time limited, which means that those with the certification must fulfill ongoing educational requirements to keep the certification current, and the criteria for certification is recognized in the community.
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.
Your vehicle's Underhood Emissions label can provide you with information regarding the type and requirement of this component. If your vehicle requires a catalytic converter it must be present, installed and functioning properly. 95% of vehicles on the road in California are required to be equipped with a CAT. Operation: The CAT is a catalyst, it typically plays no part on how well your engine runs. The catalytic converter only begins working after exhaust has exited the engine's combustion chambers. When hot exhaust gases are forced through the catalytic converter, they contact the catalyst substrate.
