Capristo 250 cell sports catalysts Mercedes GLE (4.7/5.5 V8) 2015 - 2019 02MB09103005

Sport Cats 250cell (2 Options – This option is for the Capristo exhaust)

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 to 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 the flow capabilities of that substrate. The fewer the holes, the larger the hole must be to fill a square inch, a larger hole subsequently flows more exhaust.

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 back pressure and increases temperature for proper catalytic converter operation. In the high-rpm open-valve condition, it takes full advantage of the free-flowing characteristics of the CAPRISTO Sport Cats by 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).

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