Capristo 250-cell sports catalytic converters for Maserati Ghibli/Quattroporte Trofeo/Quattroporte GTS Maserati Ghibli from 2013

Made from T309 (1.4828) grade stainless steel and hand-polished to a mirror finish. This version includes custom, hand-stitched heat blankets to reduce under-hood temperatures while protecting the surrounding bodywork, hoses, and painted surfaces from residual heat damage.

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 that substrate's flow capabilities. The fewer the holes, 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 jar or small-diameter tube. For this reason, CAPRISTO Sport Cats are packaged in 5.2-inch packages to maximize exhaust gas flow and valved exhaust system operation.

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

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

Capristo Exhaust emphasizes that you should avoid revving your car while not moving! Flames that may develop from the exhaust could cause damage to vehicles and people in the immediate vicinity!

*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.
