Help - Which Under Floor Cat?

  1. #1
    Just been out to swap the exhaust manifold stud/nut on the vtr.

    The manifold is cracked in 2 places on the top half (has been welded already) so will need replaced before mot.

    In my garage i have the following though;

    - Piper Exhaust Manfold.
    - Mk1 Magnext decat full system.

    I was going to fit this but for the MOT get an under floor car to swap with the decat pipe but need to the know the following;

    - Which under floor cat do i need?

    I beleive the piper/magnex system is 50mm bore which is slightly larger than standard so would a vtr cat fit or would it need to be a vts one (they're a bigger bore than the vtr ones right)?

    Thanks in advance!
