prob stupid question.
when replaceing the cat for a sports cat, its the second cat which gets changed, not the one attached to the manifold/downpipe?
cheers

To fully decat then both... but many just do the center one as its easier to change back to standard should the need arise such as MOT emissions failure.
I don't think that diesel have to have a CAT.
IIRC, they only have a smoke test for an MOT.
Someone can come and correct me if im wrong
