Mine's Super Catalyzer is a catalytic converter which achieves both performance and purification functions (reduction of the toxicity from emissions). Consideration to the environment being very high in the Mine's philosophy, even a pure sports car cannot escape emission controls and with a stock catalytic converter it will definitely increase the exhaust resistance. The Super Catalyzer II promises better power and response from your engine from the mid to high rpms without scarifying the original function of converter.
