Catalytic converter regeneration involves replacing the used core with a new metallic one, restoring full functionality of the system and meeting emission standards. The ceramic coating in the original remanufactured catalytic converter for the BMW M5 CS/M5 Competition 2017- provides high temperature resistance and optimal conditions for catalytic processes. Thanks to the different RFC cartridge capacities (200 cpsi, 400 cpsi, 600 cpsi) and the use of an S-type cartridge with three cores, the catalytic converter features enhanced performance and durability. In addition, the ceramic structure improves exhaust gas flow, which promotes more effective emissions cleaning and increases the overall efficiency of the exhaust system.
- 400 cpsi - reduced risk of engine error, in many cases works without interference with the second probe.
