That's good 
Nice Jag provided dedicated extraction pipe, as said I don't think I got it all via dip on VW.
The XJ 3.0 is same lump as in XF?
XF's are much more within budget
Same basic lump as the 3.0d in XF, but in XJ, only available in full fat tune, whereas most XF 3.0d are the halfarsed 230bhp variants, its the S variants that have the 270/300bhp.
Costwise, I was looking at Portfolio S XFs, and struggled to find a good one for what I was prepared to pay. When I say struggled, I mean completely failed, hence I don't have one. Which is what made me look at XJs, and XJ Portfolio 3.0d is the most common model. If you're looking at 1st gen Luxury/Luxury Premiums with the halfarsed 3.0d, they are common and thus cheap.
