Jaguar Catalytic Converters (Pair) – High-Performance Jaguar XK 4.0 Catalytic Converters
XKR 4.0 Catalytic Converters – High Performance 200 cell catalytic converters
The standard Jaguar XK 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 XKR 4.0 Catalytic Converters have 200 cells per inch, these Jaguar XK Catalytic Converters fit both the Jaguar XK and XKR. These Jaguar XK Catalytic Converters are integrated into a large-bore downpipe. As such they reduce back pressure substantially and increase flow rates, they are particularly effective on Jaguar Supercharged engines, and when combined with other Paramount Performance parts can push the Jaguar 4.2 XKR past 475bhp.
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 XK Catalytic Converters is around 22-25 bhp across the midrange.
When it comes to catalytic convertors, like many things in life. You get what you pay for. Many aftermarket suppliers fit small 200 cell cats because they are cheap. Often made to poor or unknown standards with no testing or documentation. Why is this important. Because poor cats melt and fail. We have seen numerous cases now where small low volume catalytic converters have melded, blocking the exhaust, resulting in engine failure.
This is a well know and documented issues on high performance Jaguar cars, especially those that have been tuned. It is really important to understand the quality of the parts being fitted to your Jaguar. Paramount only supply and fit cats with HJS TUV German approved and manufactured euro 5 cat internals that have been tested and certified to 350bhp per engine bank, 700bhp combined.
