Hi guys,

Just back from getting my freelander 2 MOT'd I hear a metal knocking underneath, I have a quick look under and this was hanging off my exhaust, It seems to have been welded directly to the exhaust. Is this correct?

I would say yes.
Looks like the hanger. usually goes through a rubber mount that locates on a similar pin on the body/chasis.

Do you know of a third party replacement?

Just have a local exhaust fabrication place weld a new one on.  Hyundai Ioniq 5 Ultimate. The family car.
2009 Rimini Red SE TD4. Gone.
2006 Tonga Green i6 HSE. Gone.
Audi A5 convertible, my daily driver.
1972 Hillman Avenger GT, the project.

Just tested they gave it a good old pull then lucky it fell off after as people said i quick weld tack and it’s ok.
