The BMW M4 has been marketed since 2014. During the development of the BMW M4, many parts have been built, such as the catalytic converter. The catalytic converter would lead to the exhaust stream being insufficient for the catalytic reaction. A faulty catalytic converter can lead to poor engine performance. It can also lead to a rattling noise in the engine and engine misfires.
Although the BMW M4 has lots of parts, the catalytic converter still needs repair and maintenance after a long time of usage. Signs of a bad catalytic converter include poor engine performance, black exhaust smoke, a bad smell from the exhaust, and the check engine light on the dashboard. The removal process of the BMW M4 catalytic converter is as follows. Disconnect the upstream and downstream sensors. Next, remove the nuts from the flanges connecting them to the rest of the exhaust. Then, remove old exhaust gaskets. Finally, disconnect exhaust hangers (if needed). We guarantee car buyers nice shipping criteria.
