Hi guys,
Well, I've dropped in a few times over the last while to find answers to various things, but otherwise not been around for a while.

On the big plus side, the RR is still just trucking on. It's been more-or-less my daily driver for the last couple of years and just keeps on doing its thing. I know I'm asking for trouble in saying that....

Just passed it's MOT last week with 2 or 3 advisories - one of which was the exhaust having a mild leak. I also know that my front CATs are knackered (but at least they're quietly knackered, and not making that horrible tin-can noise any longer..) I've also grown too tired of the howling and roaring caused by the previous owner's centre silencer delete.

So it's new exhaust time, or at very least the front pipes and centre silencer. The problem is I find various part numbers for the down pipes. My VIN is A448*** and I get WCD105350, WCD105360, WCD000860.... and I can't readily see any difference. They all seem to say they're OK for a 4.0L V8 with CATs.

Can anyone point me in the right direction please? If there are any pitfalls/obstacles to doing this job I'd also appreciate a 'heads up' - I've seen some references to a gearbox cross member?

Any help and advice gratefully appreciated as always.

Ta.

The earlier numbers supersede to the WCD000860, the other two (105350 and 105360) are for US models with post cat lambda sensors. So if you get sent one of those, you'll need a couple of bungs (or old lambda sensors) to plug the holes.

Some of the aftermarket ones come in 3 pieces and separate after the cats, they can be changed without dropping the gearbox crossmember. Most come in one piece so you do need to drop the crossmember to get the old one out and the new one in.

I got one for mine from Maltings Off Road (https://maltings4x4store.co.uk/categories/land-rover/range-rover-p38/engine/exhaust-system.html) but the only one they list currently shows the US part number so will likely have the extra holes for the post cat sensors.

Plenty on eBay though, https://www.ebay.co.uk/sch/i.html?_nkw=WCD000860&_sacat=0&_from=R40&_trksid=m570.l1313

Brilliant - thanks very much indeed - I do appreciate it.

The JLR parts finder did show some for overseas markets, so I avoided those, but it was far from clear.

I had also wondered about those bosses/holes on some of the pics, and was going to go out and lie underneath the car to see what the story was - but not a great day for lying under cars today!

I got them for my V8 4.0 from BM Cats.

If you're restoring the missing centre box, check the lengths as shown on the BM website. They do vary from different manufacturers. I had to return one pair to All Parts, because the CAT's were about 50mm too short.
