Installation and Usage

Downpipe replacement on the S63 is complex and involves working around the turbochargers, oxygen sensors and tightly packaged exhaust components. Engine software changes may be needed to avoid warning lights. This work should be carried out by a specialist workshop with experience on BMW M vehicles. Check for exhaust leaks after installation and again after the first heat cycles.
