H&S certainly would be able to replace it with a bit of pipe and flange, or alternatively they could weld in a new cat. They use high quality german made cats that cost about £400 though so that + welding/labour you are probably taking £600, but worth asking. Having the cat in the manifold means it lights up quicker and easier to pass MOT. the H&S item is only 100 cel but its enough when hot. You get what you pay for.  

The EGT readings that you can read on OBD readings is via the O2 sensor but this is the temp the element is running out , it is shielded from full exhaust gas flow so I would believe that temp.
 
SC car seem to run high EGT. Manufacturers CATS are far better quality than any of the CATS brick used on after market kits unless you spend a lot of money so they seem to last a lot longer when running on a FI car. Running the after market CAT as far away from the engine is the best way to make them last but this also causes issues with keeping them hot enough for MOT emission testing.
Thanks
 
 
 

Mine's blown a few times too - "P/POINT 1" in the internal box IIRC (it's labelled up, no need for the manual). Or maybe "P/POINT2"? Whichever fuse is blown 
HTH
 

Wonder how the Cobra will hold up, much the same price difference between catted and not... Oh well, always got the stock one to fall back on!
