CAT hole

After having no problems on my 2000 mile road trip over the last couple of weeks, on start up yesterday I could hear a bit of an exhaust blow.
On first investigation I thought that this stud had perhaps worked its way out, it certainly isn't in properly.

But once the engine was on I was not sure how I missed this hole.
I will try to clean up the surrounding area and try to weld on a patch, or look for a second hand cat if that fails.
The CAT looks like a real pain to replace, there seems to be no access from the engine bay.

Tonight I used a flap disc to get to solid bright steel before trying to weld on a patch. The end result is a hole to big for my poor welding abilities.
I'll drop in to Davy the welder on Friday to see if he can tackle it.
The upside is that the car now sounds like a real big American muscle car.
