Hi Guys.
I read somewhere that if you remove a fuse (19 or 9?? not sure which.) from the fuse box behind the back seat. The valves in the exhaust stay open. You can enjoy the full sound of the V8 at any revs. Normally these valves open only when you floor it. Any one done this?

I've done it. It doesn't give you the full roar of the V8, there's still catalytic converters and baffles in the way. It makes it slightly louder, but doesn't give any more definition. You're going to have the change the exhaust if that's what you are after.

My amber engine light also stays on with the fuse removed

So was it fuse 9 or 19, Johnnnnnnyy?

I'm not 100% sure, my Jag mechanic did it while the car was having some other mods done, I'll find out for you and report in

19, but it is only relevant to a supercharged XK. The non supercharged XK's still have fuse 19 fitted but it does not do anything as the actuators / valves are not electrically operated !!!

I have a 2011 XKR and removed fuse 19 and has made a noticeable difference to the exhaust note, even when starting / idling. Under mild throttle it sounds very 'raspy' and at a certain point it gets very loud.

Its easy to remove the fuse and hasn't left any warning lights on. Remove the horizontal leather partition that straddles the tunnel between the two rear seats (lifts off with a bit of a tug). Then pull the rear vertical leather partition between the two rear seats forward very slightly whilst pushing up slightly at the same time towards the roof. Both leather partitions are held on with some plastic 'male bayonet style' clips so you need to break the hold they have with the female receivers on the frame underneath. You cant see them as they are behind the leather partitions.

Fuse 19 is clearly marked and is in the right side of the fuse box - Its also red in colour. There is also a 'fuse puller' situated in the top right hand side of the fuse box which clips over the fuse to help you pull it out.

I'm not particulalry sure if an aftermarket exhaust is worth the extra £££ to make it any louder / growlier (is that a word?). Its an easy thing to do so give it a whirl and if you dont like it, put the fuse back in. Shimples...

Aftermarket exhaust would certainly help the XKR lose some weight- about 25-27 lbs with a few systems.

It's completely different. Once you hear an aftermarket exhaust in the flesh, it makes the standard exhaust sound tame. Depending on what exhaust you chose, you'll hear a very deep burble upon start up, and a gorgeous throaty classic V8 muscle car thrum on gentle cruising. Plant your right foot and you get an amazing 'bark' as she hits the sweet spot. All very addictive.
The standard exhaust has catalytic converters + all the worlds rules and regulations (emitions) stopping it sing.
My new exhaust will be fitted next week

 

[mickpsu]

Sounds interesting. What sort have you opted for?

 

[johnnnnnnyy]

it's being fitted hopefully this week, or next. I'll post all info + pics and audio so you can hear
