My car has a miltek decat at the moment but its nearly mot time so will be putting a new cat on.
The only problem is how to fit the new cat, it has a flange at the manifold end which is fine but at the other side there is nothing, does it just fit in or am i missing something??
Im telling you that some full systems come with specific fittings i.e just a sleeve. The OE cats have flanges on both sides, others need a flange welded on. Does your centre section have a flange or a sleeve?
