Capristo 250 Cell Sports Catalytic Converters Porsche 718 Spyder/GTS/Cayman GT4 02PO01003019

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 gas.

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 flow characteristics of the CAPRISTO Sport Cats by optimizing the 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.

**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 US 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 intended 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 can be used in their region. Capristo Automotive emphasizes that you should avoid revving your car when not in motion! The resulting exhaust flames could cause damage to vehicles and people in the immediate vicinity!**
