Up top!

Behind the turbo heading down towards the down pipe.

More like a guaze than a cat. not much value in removing it.

There's no point, it's not restrictive.  :)

So how much more low down grunt has it achieved by doing the DeCAT

Smog test only. They are looking to bring in a visual check that the cat is present but no other test.

Removing it's innards helps the acceleration from a standing start and adds a couple of MPG on motorway runs. Best to do this mod then get it remapped, though it all depends if your VP44 lasts long enough to get to a remap stage.....  :'(

The major cause of VP44 issues is problems elsewhere......
