As the title says - a couple of questions about the stock exhaust system. Curiosity mostly. There doesn't appear to be much info out there on cars based on the NA engine.
Firstly, does anyone have an underside picture of the exhaust setup? I've done some googling but I can't tell for sure if it's the same as the other dual exhausts run on the XF or not. Yes I do have one but I don't have the facilities to get an underside picture. I imagine it's different to the one on the XFS diesel but might be the same as the supercharged?
Does anyone know if it uses any active/passive valves at all?
Many thanks,
Simon

I've asked the same question and only one response suggested to call MINA as they have them for the XFR..But I too wasn't sure for the NA 5.0L version...
BTW..are you sure you have a 5.0L and not a 4.2L ?

Err I'm not getting you here, are you suggesting MINA has information on the stock setup as some people like to apply it to the XFR? That's a weird proposition to me if so! Haha!

I definitely do. One of not very many here in the UK!

..I've been under mine on a lift..and there is nothing strange and no valve chambers either that I could see..straight back from the cats...Is pretty typical with the resonators and then the mufflers near the rear before the outlet ports

Cheers for taking a look. Your exhausts have the dual ovals then? Just checking because OzXFR's workshop manual has quad ends.

And the exhaust tips? I've got dual ovals, not quads. Does your manual still apply to my car?
Mine has dual ovals. Yours may be a bit odd, since I thought all 09s were 4.2. Your dual ovals may be more of a product of the year than engine, so maybe yours is more like mine than theirs.
BTW, no exhaust valves in the 09s. The mufflers are smaller too.
Like OzXFR said. There is no difference in 5.0 exhaust except the valve. The piping to the axle is the same. The piping to the axle on the 4.2 is different. So when looking for exhaust, it's only a matter of 4.2 or 5.0.
So for interest and potentially amusement we have a potato quality rear of jag shot and the price list pages! I have the collection booklet as well which is all the pretty publicity.
It was actually a Jaguar fleet car, so they may have had access to the newer MY before other people? Not sure if that'd given them a custom brochure though. Of course got these booklets from the previous owner who was the one who got it from Jaguar.
If it makes any difference too - I'm in the UK. Car was first registered in June 2009. The DVLA info for the car also shows a 5000cc engine.

Do mine look exactly like yours then? If so, that explains things

My manual is for the 2010 & 2011 5.0 V8, in particular the SC version (although it does cover the NA as well), so it may not accurately depict the exhaust system on a 2009 model 5.0 NA.
As others have noted I thought the 5.0 wasn't available until the 2010 MY, but it seems that it become available in some markets on the late 2009 MY.
But one thing seems for sure, the 2009 NA 5.0 exhaust system came with completely different rear mufflers to the XFR - different boxes, different tips and no passive exhaust valves.

Thanks guys, this is pretty damn interesting!

May I ask you send me your VIN, for me every interesting to see 5.0 in 2009MY car
Hi Simon!
Many thanks for VIN.
As for me you have unique vehicle with 5.0NA and 6HP26 gearbox, this combination is the same as on XKR
You have 2010MY car, but was produced Jan. 30, 2009

Fascinating and strange! I wonder if anyone has a technical info for this one? Or if it is the same system as OzXFR posted, but with different tips and no valve?
As an ex-Jag fleet car they may have had access to the new MY before anyone else.

EDIT: And of course thanks for that 08292 - I've run it through a VIN decoder before but I wasn't able to pick out the subtleties you are.

From factory were installed exhaust rear boxes with oval ends and w/o valves as on XFR.
You can find the XFR rear boxes with double ends and with valves, or find XFR-S rear ends w/o valve.
