Capristo 250-cell OEM Sport Catalytic Converters Mercedes GLE (4.7/5.5 V8) 2015 - 2019 02MB09103006

These high-performance sport catalytic converters feature a 250-cell-per-square-inch substrate made from the highest-quality materials available today, 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 are packaged 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 increasing temperature for proper catalytic converter operation. In the high-rpm, open-valve condition, it takes full advantage of the free-flowing characteristics of CAPRISTO Sport Cats by optimizing high-energy exhaust at the ideal temperature and backpressure for maximum performance.

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.
