Capristo 100-cell sports catalytic converter for Mercedes AMG SL63 (R231) Biturbo 2012-2020 02MB03603007

These high-performance sport catalytic converters feature a 100-cell-per-square-inch substrate made from the highest-quality materials currently available, designed to improve airflow for your vehicle and increase performance.

The cell count of a catalytic substrate refers to the number of holes per square inch and is a direct indication of that substrate's flow capabilities. The fewer the holes, the larger the hole must be to fill a square inch; a larger hole subsequently allows more exhaust gas to flow.

All that high flow won't help if the substrate is "squeezed" into a small-diameter container or pipe. For this reason, CAPRISTO sport cats come in 5.2-inch packages to maximize exhaust gas flow and valved exhaust system operation.

The CAPRISTO valved exhaust system helps low-end torque by providing exhaust backpressure and increases temperature for proper catalytic converter operation. In the high-rpm open-valve condition, it takes full advantage of the free-flow characteristics of the CAPRISTO Sport Cats by optimizing the high-energy exhaust at the ideal temperature and backpressure to maximize performance.

These catalytic converters can easily be retrofitted to a CAPRISTO exhaust system or any system that fits directly over the OEM exhaust.

*Recommended for off-road and track use only*

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

To disable a recurring CEL, you will need to tune the ECU or use 02 sensor extensions.
