    passed first mot

    despite my worries on emmisions, the car passed its first uk mot with flying colours - no advisories:cool: he also commented that the emmisions were low as hell, which is probably testament to jezs mapping! de-cats now back on, heres to another year:D

    De-catting

    If you run a de-cat pipe on your S-15 will it fail the mot? i ask this because irrespective of a 300ZX age, when i took that to a garage they had to test it as a non cat equiped car because they have not details on the emmisions for that type. just wondering if it was the same for one of these?
