Capristo 100-cell sports catalytic converters Porsche 718 Spyder/GTS/Cayman GT4 02PO01003012

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 for maximum 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.

**The use of sport catalytic converters, replacement pipes, and manual valve controls (CES-3, EVCU-1) is not permitted on public roads in some states in the U.S. and other countries. Be sure to observe the legal regulations of your respective country/state. Sport exhaust systems not approved for use on public roads are intended for racing purposes only and are designed for use on private racetracks. Use on public roads is at your own risk. Before installing an exhaust system, the buyer must ensure that the system is permitted in their region. Capristo Automotive emphasizes that revving your car while stationary is important! The resulting exhaust flames could cause damage to vehicles and people in the immediate vicinity!**
