Porsche 718 Spyder/GTS/Cayman GT4 - 100 Cell Sport Cats

Made of T309 (1.4828) Grade Stainless Steel and Hand-polished to a mirror finish.

These High Performance Sports Catalytic Converters feature 100 cell per square inch substrate fashioned from the highest quality materials currently available designed to improve air flow 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 lower the count of holes the bigger the hole need to be to fill one square inch, a bigger hole subsequently flows more exhaust gasses.

All of this High flow will not help if the substrate is ‘squeezed’ into to small a diameter can or pipe. For this reason, CAPRISTO Sports Cats come packaged in 5.2 inch packages to maximize exhaust gas flow and operation of the valved exhaust system.

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

*Recommended For Off-Road and Track Use Only*

Replacing Your OEM Catalytic Converter/s may trigger a CEL (Check Engine Light).

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

**The use of sports catalytic converters, replacement pipes and manual valve controls (CES- 3, EVCU-1) are not permitted on public roads in some US states and other countries. Please be sure to observe the legal regulations in the respective country/state.  Sports exhaust systems that are not approved for use on public roads are intended exclusively for racing purposes and are designed to be used on private racetracks. Use on public roads at your own risk.  Before installing an exhaust system, the buyer must ensure that the system can be used in their respective region.  Capristo Automotive emphasizes that you should avoid to rev up your car while not moving! The exhaust flames that may occur could cause damage to vehicles and persons in near proximity!**
