hi i have a lc and wanted to decat it,i have added a cupra r exhuast from back to cat,and was told that if i wanted to keep cat and do a proper decat then i had to get hold of a flange so that the new pipe can fit on it,i have tried looking but cant find one,seat told me that i have to buy a new exhuast/turbo manifold and would cost around 300,which is pointless,may aswel buy a new exhuast for that,any ideas please
