  2. #2
    Your cats in the manifold so yeah it will decat it.

  4. #4
    Yes, but you can get a cat that goes under the car, typically from a mk1, but also on some of the early mk2's and use that and it should be fine

    As above, cant get a cat in the middle section, or if you wanted to refit the standard manifold, come MOT time, and enjoy the gains of a 4-2-1 and Decat all in one
