When I bought the manifold and cat it was advertised as having no problem passing a MOT .
The first Cat had the TRACK USE ONLY NOT FOR ROAD USE buffed off.
The replacement CAT still had it ,when I questioned them ,I received a call saying they had missed that one as it was going out without a manifold .
I still have their advertising from 2016 when they were openly selling that Cat for road use .
