  • Jaguar XJ and XJR 4.2 Catalytic Converters

    Jaguar XJ Catalytic Converters (Pair) – High Performance Jaguar XJ 4.2 Catalytic Converters

    4.2 Jaguar XJ Catalytic Converters – High Performance 200 cell catalytic converters.  The standard Jaguar XJ and XJR catalytic converters have 600 cells per square inch, these original standard cats can be very restrictive in their gas flow.


    Paramount’s high flow  Jaguar  XJ Catalytic Converters have 200 cells per inch, these Jaguar XJ Catalytic Converters fit both  the Jaguar XJ and XJR. These Jaguar XK Catalytic Converters are integrated into a large bore downpipe, they reduce back pressure substantially and increase flow rates, they are particularly effective on Jaguar Supercharged engines.


    Emission levels remain fully road and MOT legal. Performance Hi-flow Jaguar Catalytic Converters and Sports Cats work exceptionally well on re-mapped (chip tuned) engines. The power increase delivered by our Jaguar XJ Catalytic Converters is around 22-25 bhp across the midrange.

    These Jaguar S-Type 4.2 Racing Catalytic Converters also approved and tested to 600bhp. Using German TUV cat matrixes, they are not the cheap small Catalytic Converters used by many suppliers which burn out and fail in just 2-3 years. Or worse, melt block the exhaust system, potentially causing catastrophic failure of the engine.

    If you are going to change your Catalytic Converters be sure to change them with a part of at least teh quality of the OEM original. Do it once and do it right.
