Sports catalysts 250 cells Capristo Porsche 718 Spyder/GTS/Cayman GT4

These high-performance sport catalytic converters feature a 250 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 the flow capabilities of that substrate. The fewer holes the larger the hole needs to be to fill a square inch, a larger hole subsequently lets more exhaust flow.

All this high flow won't be It helps if the substrate is "squeezed" into a small diameter container or tube. For this reason, CAPRISTO sport cats are packaged in 5.2-inch packages to maximize exhaust gas flow and operation of the valved exhaust system.

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

*Recommended for off-road and track use only*

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

< /p>

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

**The use of sports catalytic converters, replacement hoses and manual valve controls (CES-3, EVCU-1) is not permitted on public roads in some US states and other countries. Please make sure to observe the legal regulations of the respective country/state. Sports exhaust systems not approved for use on public roads are intended for racing purposes only and are designed for use on private circuits. 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 his region. Capristo Automotive emphasizes that you should avoid revving your car when you are not moving! The exhaust flames that may develop could cause damage to vehicles and people in the immediate vicinity!**
