Drooping Exhaust Problem (XJS V12)

Drooping Exhaust Problem (XJS V12)
As you will see from the Photo, one of my straight pipes is 'drooping' because the section with the swage has not been pushed completely home in order to make it rigid.
When I did push the swage section home, all the 'drooping' disappeared and everything was fine, except that the support pegs that hold the Silencers up, fell out of their mountings.
The straight pipe on the other side, is exactly the same length but someone has put a repair section in to extend that swage by another 2 inches (approx)
So I would like to do the same and put an extending repair piece on this side, which you can buy online for £4-49.
As I haven't got one of those gadgets (micrometer?) for measuring the outside diameter of the pipe, please could someone provide me with this measurement.
Repair Sections come in these sizes, so which one would I need?
50.8mm - 2 inch
54mm - 2.125 inch
57mm - 2.25 inch
Just before someone mentions it and suggests I buy a new pipe, I'm having a stainless steel one made up, which won't be ready for a while, so this will keep me on the road till then.

54mm is sounding very promising!
As you say 'Greg' will hopefully give me a double check on that and 'When' I get her out of the garage.
I will slide a big adjustable spanner over the pipe and then measure the distance between the jaws. (which I've only just this minute thought of doing) doh!

Greg has been instructed by the Management to clean her car this afternoon. The "measure the jaws of an adjustable" idea is wonderful! I was going to suggest a piece of wood and two right angle pieces. Just shows what lateral thinking can do OB. Also, I have a Bell stainless item so I am not sure the O/D is the same as OEM.

'Grant' aka 'The Wizzard Of Oz' was bang on! with 54mm
I did the thing with the spanner and although I'm rubbish at Metric Measurements, it came out at 54mm!
Good luck with the 'Managements Car!' and Thanks for your encouragement which is always a big help in its own right.

I feel sure if ever your motivation falters, your fan club in the Northern half will send emergency supplies of JD. Seriously, though, this is great news for my boys!

Don't 'Peak too soon!' 'Grant'
I'm trying to get the good 'Down Pipe' off my Scrap XJS V12 to put on my Grey XJS.
So far the Two nuts in the Engine room have taken me 2 hours to get off!
You know that 'Stuff' you spray on to stop bleeding!
Guess what, it doesn't work!
Should I have taken the whole manifold off and then removed the 'Down Pipe' when it was out of the Car?

When they are that frozen in place, that is the only safe way. Still a mongrel task, but blood loss is reduced a tad.
I changed an ABS sensor on the Black Beast last night, and slack as I am, I reached under the wheel, and got it out of the hub, then full lock the other way, and reached for the loom connector, THANKS JAGUAR, that sucker is tucked up in the inner sanctom of the plastic liner, and I really was NOT taking that wheel off, so kept reaching and swearing, and when done, I retreated to the "Lazyboy" with a glass of necta, and the wife commented on the BLACK mark on my arm, hinting at grease I missed washing off. NO, its a bloody bruise, fair dinkum.
Had I taken the wheel off, and done it that way, it would have been faster, easier, less swearing, no bruise, but where's the fun in that. It was 38C at 11PM last night, so I perspired like a marathon runner. Healthy activity this Jag maintainence.

Having got the Two worst nuts off! (the hard way!) I 'think' I might be able to get to the other Two from underneath the Car, with a long extension socket with a 'wobbly' on the top.

Why do you guys Insist on doing things the hard way??! I understand the need for an occasional challenge but this is ridiculous!
I wouldn't have lasted in my work for one season let alone 10 if I didn't find the easy way to do Everything -- not to mention a Really Good chiropractor.

haha, sorry I don't know the diameter but mine does this. I patched it and it lasted a few years, but it makes a distinctive sound nowadays. You will know if it pops all the way out, mine did on the highway lol. it only moved down a few inches, so its not like it will spike the pavement.
Going to get a new pipe to weld in and put the proper clamp back on it,hope you get yours back together alright

That's the very thing I was trying to think of the name of but I thought that they would probably cost a fortune!
But since they don't I'm definately going to order one right now, so thanks for the heads up, on that.

Although which ever way you go, removing an XJS down pipe, is not an easy job, as there is hardly any room to work.

But for work I only use Mitutoyo calipers and micrometers, both metric and imperial. I have had my work ones since 1983 but they cost me 2 weeks wages(apprentice pitance) for the set of four back then. And still use them daily 32 years later.
I keep this washer on my work key ring that caused $25k damage to a multi million dollar printing machine. It reminds me that not everybody calibrates their tools correctly. An extra 5.9 thou (0.15mm) an a machine with 3 thou(0.075mm) tolerance can cost you your job and your employer a migraine.
But for home use the cheap ebay tools serve the purpose.

That's very good advice Clarke
An Uncle of mine had one of those 'Caliper Things' back in the day and being a precision instrument, it cost him a fortune!
Until you happened to mention it, I didn't know such cheap ones were available, which are perfect for everyday stuff, like making sure you buy the right clips to go on your exhaust.
I have lost count of the number of times I could have done with one of those, so now just waiting for it to arrive.
