V Band for 2.2tdci puma turbo-back exhaust

[Toxic_Avenger]

Anyone got any pro-tips for what type of V band (size, style) I'd need for a turbo back exhaust? I'm mainly looking to procure the flange to use with the standard V band clamp.
Is it 2.5" like the rest of the system?

It would save me getting it all undone just to check...

We reused all the off turbo fittings.

Alright, so I decided not to be a lazy *****, and got under it to git'er done. Goal was to remove the Catalytic converter. I'll admit, it's a bit of an ordeal- main issue is cat body is approx the same size as the engine block to chassis rail width.

The cat converter heat shield comes off with 2x 10mm bolts, 3x 8mm bolts (a little rusty from heat cycles)
10mm nut on V band clamp. - Dimensions to follow.

To remove the cat assembly,
Remove driveshaft - 8x 9/16" bolts and nuts (pro tip- get a cheap 9/16 spanner, cut in half. Chamfer a 45 on the ring end, and use the open end as-is. makes access issues a non-issue
Removed cross member - 4x 13mm bolts thru the chassis (top most), with 15mm nuts on the inside of chassis. 4x 13mm bolts that secure lower crossmember to chassis- via welded captive nuts. Gave it a quick rust converter treatment and new paint to prevent any future issues.

Getting the cat converter out without too much drama was wishful thinking...
FSM recommends undoing top nuts on engine mounts and jacking the engine UP, Others (tombie) cut the pipe and bracket to get it out the bottom
I'd hoped to get through it with no cutting, but but could not manage it. Without a lot of the water hoses and other engine parts being removed, it would be hard to get a good socket or spanner on those bolts. So I got the sawz-all out and cut the bracket and bottom pipe, and it came out without too much of a fight. I'll weld on a flange set to make re-install easier later.

You can get it out by cutting its mounting bracket off and then it will just make it through.

Nothing else removed.

Local exhaust shop not able to help with the exhaust side turbo flange for the V-clamp.
Cutting the flange off the cat converter is not an option.

Anyone sourced one? And where from?

Thinking about it, exhaust guy probably played the ignorance card when I rocked up with a hacked up cat converter under my arm looking for parts...

Trolling the exhaust wholesalers websites and catalogues, appears they are called a 'Lipped Flange' 20 degree seems to be the norm.
Will try get my hands on one to see if it works.

I machined a standard type flange to mate up with the taper on the turbo.
If you get stuck I can make you one.

Shouldn’t need to buy one.
I just flared the pipe to suit.

I don't have access to the flaring tool, trying to make this almost entirely an at-home job. I'm happy to buy the components to use as a training tool for pipe fitting / welding. I've got to get some hours up on my new TIG welder somehow [bigwhistle]
