Downpipe Decatalysts Capristo Mercedes Mercedes AMG E63 S/W 212 02MB02403005

The CAPRISTO valved exhaust system helps low end torque by providing exhaust back pressure and increases temperature for proper catalytic converter operation. While in the high RPM open valve condition, it takes full advantage of the free flow characteristics of the CAPRISTO downpipes optimizing high energy exhaust at the ideal temperature and back pressure to maximize performance.

*Recommended for off road and track use only*

Replacing the OEM catalytic converter may activate a CEL (Check Engine Light).

Disabling a recurring CEL will require ECU tuning or the use of 02 sensor extensions.
