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 XJ 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 XJ Racing Catalytic Converters also approved and tested to 600bhp. Using EU certified 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 the quality of the OEM original. Do it once and do it right.

Sports Catalytic Converters, de-cat and sports cats  – Paramount Performance list a large range of catalytic converters. Some are TUV / EC approved. However, others such as the IPE and Armytrix systems are manufactured outside of Europe and so may not be EC approved. For this reason, some sports catalytic converters and all “De-cat pipes” for sale on the Paramount site are sold for motorsport and off-road use in the UK and EU, and not for road use. Our expert team is on hand if you need any help choosing the right catalytic converters for your use.
