BMW E39 5-Series Exhaust Replacement | 1997-2003 525i, 528i, 530i, 540i

Описание: The BMW E39 is a very fast machine. One of the ways this is accomplishes is with a high volume, high flow exhaust. These units are large and sturdy but can corrode from high moisture and road salt contamination. These can lead to louder exhaust noise and in some states a failed emissions compliance inspection. Part of this exhaust system is the catalytic converters. These catalytic converters keep your vehicle emissions compliant. The OBD-II diagnostic system in your engine control unit compares the front and rear oxygen sensors to see if the catalytic converter is doing its job. If it is not functioning the control unit will flag a code and turn on your check engine light. The exhaust may also have to be removed to service other items such as the drive shaft and parking brake cables. In this tech article we will review all the steps to remove the entire exhaust system.

It is entirely possible that fasteners and components can rust to a point where they are no longer useable. You may have to provide heat and/or destroy hardware to remove your exhaust. It is a good idea to use extensive safety practices when working with heat and wear eye protection to prevent loose rust from falling into your eyes.
