Wanted - Cayman S 987.1 headers

Are you sure that the problem is with the pre-cats which are integral with the exhaust manifolds? The main cats are integral with the silencers.
You could try contacting Porsche a dismantler like 9Apart:

That's a good question!
The error code reader gives out P0431-1 code saying that catalytic converter efficiency is below threshold on bank 2.
Headers are corroded quite a bit as well.
This tells me that headers need replacing. However, I might be wrong and I would really hope that replacing O2 sensors would fix it...

My Cayman S sport kept throwing up engine light .
Have you tried to delete the warning light? If it's the cat it tends to reappear after the 3/4th journey out.
Mine was the warm up cat attached to the manifold someone before me replaced the O2 sensors which never fixed it hey ho.
An in depth investigation is needed with sophisticated cat temp machine to see if temp spikes or erratic.
If you need the manifold cat it won't be cheap brand new from Porsche finding a good used one is like hens teeth and still a fair price I was lucky getting one from Porsch apart getting on a waiting list .
Bare in mind the bolts will rusted to bits, again I was lucky a previous owner had replaced all the exhaust bolts so easy on and off for the mechanic.
Another option is getting sports cats which my mechanic advised against it will need an ecu reflash he said he has still had trouble throwing up engine light on some he has done.
Find out before spending money if it's the manifold cat
I went for the good used one no problem since it's the least expensive root
Your still looking at £500/550 if the bolts are ok .
They are rare to find people jump on them as soon as available be quick or get on some lists of Porsche breakers.
Good luck

Thank you for information, this is very useful.
I was thinking of buying the 200 cel aftermarket cats but it looks like it's not a good idea.
I've reached out to quite a few breakers and noone has them, it's like finding a unicorn!
I've managed to find a used bank 2 manifold in a very good condition on eBay. This is the problematic side. It's arriving next week and hopefully it will sort out the issue.
Need to keep an eye for the bank 1 manifold.

Good news you found one they are like hens teeth to find.
Sports cats not all pose the engine light coming on but my mechanic said some do some don't and still an expensive option especially if the engine light comes on after a reflash.
I just replaced the bad side no problem since so would not worry about the other side if all good.
Hope the bolts are not to rusted as mentioned.
Good luck with the fix
