Capristo 200 cell sports catalyst with Ferrari 355 thermal blankets

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.

These catalytic converters can easily be fitted to a CAPRISTO exhaust system or any system that directly fits the OEM exhaust.

We recommend purchasing our by-pass valve as well 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 trigger the check engine light .

*Recommended for off-road and track use only*

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

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