The cell count of a catalytic converter refers to the number of holes per square inch and is a direct indication of the flow capabilities of that converter. The lower the hole count, 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 converter is "squeezed" into a can or pipe that is too small in diameter. For this reason, the CAPRISTO Sports Cat is packaged in 5.2" packages to maximize exhaust flow and valved exhaust system operation.

The CAPRISTO valved exhaust system helps low RPM torque by providing back pressure in the exhaust and increases temperature for proper catalytic converter operation. While 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 fitted to CAPRISTO exhaust systems or any system that will fit directly over the OEM exhaust.

Recommended for off-road and track use only

Replacing the OEM catalytic converter(s) may cause the CEL (Check Engine Light) to go off.

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