Jaguar XK8, XKR and XKR-S 4.2 - Sport Exhaust OPTIONS (2006-09)

 XK8, XKR and XKR-S 4.2

 SPORT (2 box)




We offer two sound options both have much more efficient internal gas flow providing a noticeable improvement in throttle response for even more exuberant acceleration.

Improves heat transfer from the car and is far lighter than the factory’s system. 

The system comes with 4 larger perthed tips which deepen the sound and are the finishing touch for this sporty enhancement.  


- Cat-Back system.

- An elitist muscle rich growl throughout the rev range.

- Bolt-On fit - Precision engineered.

- Lighter weight.

- Individual Appearance – 4 perthed tips that fill the rear apron.

- Improved performance + 7 bhp and + 15 ft lbs (rear wheel).


A deeper rumble at idle and blips on the down change rising to a unique, higher pitched and crisper exhaust note at higher rpm.

We offer two sound levels;

Sport - Designed for the everyday and long distance driver, refined yet sporty when required. 

SuperSport -  Louder and suited for the driver who enjoys his car mainly just for fun offering a distinctive sound.

Jaguar XK8 SuperSports Exhaust – November 2010 – Ronni - Denmark
I am very very satisfied with the result after changing the exhaust on my Jaguar XK8 1996 to the QuickSilver SuperSport. Now it sounds like a SLR or a Lambo. 
The sound is a bit too loud when I am driving on highways but when I am driving slow in the city center and ESPECIALLY through tunnels and the hammer is dropped... Undescribeable! 
(I have been through every tunnel in a 20Km radius of the city, since the exhaust was mounted)
4 persons have complimented the sound of the car - Today. That is a bit above the average number of compliments per day. :-)
Thank you for good service, delivery and a very good product.
