Complete assembly including catalytic converters and resonated mid pipe, also known as a section 1 exhaust

Catalytic converters are the main component of your BMW's emission system. Catalytic converters are needed for reducing harmful emissions by converting them to less harmful emissions.

Even on a high performance car such as the M3, catalytic converters are standard equipment. A failed catalytic converter will commonly cause a check engine light to illuminate on your BMW's instrument cluster.

For the most part catalytic converters are life time components. However, poor maintained and poor performing engines can cause damage to the catalytic converter causing irreparable failure. A catalytic converter that has a reduction of flow by less than 5% can illuminate a check engine light.
