Capristo 250 cell sports catalysts Ferrari 355 (5.2/2.7) 02FE03003011

Made from T309 (1.4828) grade stainless steel and hand polished to a mirror finish.

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.

These catalytic converters can easily be retrofitted to a CAPRISTO exhaust system or any system that will fit directly over the OEM exhaust.

We recommend also purchasing our by-pass valve for the 355 as it helps prevent excessive back pressure and heat build-up.

The ECU will need to be reprogrammed as Sport Cats may activate the Check Engine Light.

*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.
