U dont need a cat for any uk sunny or import gtirs as the emission sheet only shows 1.4 and 1.6 sunny for a uk model and nothing for a pulsar and its not either so u only choice is to select other then it will do a default emission test co 3.5 hc 1200, now if a car fails any of these tests then there is oviously a bad problem with the running of the car but other wise if ur n14 gtir is within co 3.5 hc 1200 it is a pass even if its a m reg uk sunny gtir. Before any one says u do need a cat trust me u dont im a tester and i checked this out yesterday as i thought that a uk 1 would do but to my surprise it doesnt and niether does any sunny n14 apart from a 1.4 and 1.6 eg gti n14
