Removing your stock catalytic converter is not only illegal in most places but it is bad for the environment. This puts you in a dilemma because running a turbine requires a higher flow exhaust in order to keep back pressure low. If the exhaust back pressure is too great under boost your car will run poorly. You will damage the turbo bearings, seals or cause cracks in the exhaust housing if you boost above stock levels without a proper exhaust setup. Maintaining a clean exhaust while increasing horsepower can be obtained with the SARD Sports Catalyzer.
