Exhaust flange corroded....repair kit?

Hi folks,

The exhaust flange on my cat has corroded pretty badly on my 2004 1.8 but the cat section itself looks reusable. I assume it is original. The exhaust further back has been replaced fairly recently.

Has anyone had any joy with the flange repair kits or split flange arrangements with this issue? Check the pics please.

Cheers

James
