Video: Jaguar XK R with high-flow cats.

 Exhaust plays a huge role in your car's performance and personality. We recently had this beautiful black Jaguar XK R at our shop to remove the factory catalytic converters and replace them with special high-flow performance cats.

The rest of the exhaust remains factory, but this little change results in a much deeper tone, less back pressure and a few extra horsepower for this British beast.

Check out the video below to see the before and after videos and see how high-flow cats are one quick trick to giving your car a beefier sound and some added performance.
