I’ve put a request in to the forum sponsors for a unit if they have one but there are some attractively priced new units out in the big wide world. However there’s no point getting a new one if the catalyst parts are ineffective. So do off the shelf pattern parts work? Or do I avoid them like the plague? Answers on a postcard.
Good running engine should pass emissions even without cats, obviously cats are required by the rules so would still fail MOT even if it passes emissions test

If the cats are I would just cut out flexi piece and weld a new one in. Cheaper and you get to keep original cats.
