Capristo 100 Cell Stainless Steel Sports Catalytic Converters Aston Martin DB9 V12 2004 - 2016 02Am01803004

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

These high-performance sport catalytic converters feature a 100-cell-per-square-inch substrate, made from the highest quality materials available today, designed to improve vehicle airflow 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 hole count, the larger the hole needs to be to fill a square inch; a larger hole subsequently allows more exhaust gas to flow.

All that high flow won't help if the substrate is "squeezed" into a can or tube that's too small in diameter. For this reason, the CAPRISTO Sports Cat is packaged in 5.2-inch packages to maximize exhaust gas flow and valved exhaust system operation.

The CAPRISTO valved exhaust system helps low-rpm torque by providing exhaust backpressure 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 backpressure to maximize performance.

These catalytic converters can be easily mounted on CAPRISTO exhaust systems or any system that fits directly over the OEM exhaust.

*Recommended for off-road and in-country use only track*

Replacing the OEM catalytic converter(s) may Turn off the CEL (Check Engine Light).

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