Jaguar XJ Catalytic Converters (Pair) – High Performance Jaguar XJ 4.0 Catalytic Converters

4.0 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.

The Paramount Performance Jaguar catalytic converters are unique in the market. The Paramount 200 cell cats use a matrix that is EU certified and carry an “E” testing and certificate number. No other Jaguar aftermarket cats we know have are correctly tested to be used in UK and Europe. If you are looking at other products, its worth asking if they carry and “E” certificate number – a legal requirement in the UK. They will also, as you would expect, pass a UK MOT emission test. And have been tested and proven to run over 670bhp.

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.

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, all sports catalytic converters and “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.
