Sport cats Capristo Rolls-Royce Cullinan

02RR12903001

Sport cats for the Rolls-Royce Cullinan. The section replaces the factory catalysts of the 6.75 twin-turbo V12, which together with the turbochargers are what make the car effectively silent from the outside.

Why this section

On a turbocharged engine the catalyst section is where both flow and sound are lost first. Changing only the rear silencer on a Cullinan moves very little; opening up the catalyst section is what actually changes the character of the exhaust.

Material and build

1.4828 (AISI T309) stainless steel, hand polished, built for the OEM flanges and mounting points in Sundern, Germany.

Before you order

• Replacing catalysts can set a check engine light; ECU work or a suitable emulator may be required;
• Emissions rules differ by market, so check what is permitted before road use;
• The result is best judged together with the Capristo valved rear section, which lets you keep the quiet mode;
• Bolt-on fit, no modification to the car.

Capristo Automotive GmbH has built valved exhaust systems since 1990 and holds several patents on its valve technology.
