The 2006 - 2008 aluminum chassis Jaguar XKR 4.2L V8 Supercharged is a strong, nice sounding car, with an undiscovered potential for more performance.

Underneath the engine plastic shielding there is an intercooled Eaton supercharger system, which provides for very efficient feeding to the engine.
By eliminating the bottleneck, restrictive cataltytics, and enlarging the undersized diameter exhaust piping, the Supersprint R&L High-flowing metallic cats and full exhaust make the XKR V8 powerplant substantially stronger, and greater sounding at the same time, with the addition of an impeccable quad-tip design.
Installing the Supersprint stainless steel full system guarantees major gains in mid rpm torque, and in peak hp as well.
The subdued engine note is replaced with a high-pitched V8 scream, once the vacuum flaps go open.
In spite of the increased exhaust gas flow and the newfound power, there is absolutely no droning in the lower rpm range, for comfortable daily and long-distance commuting.
With no modification needed and a prefect fitment, the Supersprint full exhaust is the most effective bolt-on addition for the Jaguar XKR 4.2L V8.
