    These days there are virtually no vehicles that are not equipped with a catalytic converter. These parts are intended to convert toxic pollutants into carbon dioxide, nitrogen, and water, which are harmless to the environment. The main drawback to converters is that they reduce the vehicle’s performance due to back pressure, so your top speed is not as high as it could be. Cleverly designed performance catalytic converters feature special catalyst materials and construction that both make your vehicle 'green' and reduce loss of engine power to a minimum. So, you can take advantage of better engine efficiency due to improved exhaust flow, while being sure your BMW 3-Series won't fail an emissions test.

    You can't remove a catalytic converter; it's against the law. But you can reduce restriction by installing a high-flow one. Performance catalytic converters are ideal for use with other performance components meant to boost the output of the engine. In our store, you will find BMW 3-Series performance catalytic converters manufactured by leading aftermarket companies such as Magnaflow, PaceSetter, Flowmaster, Stainless Works, and Vibrant Performance.
