can someone please explain to me whether the cat is required for m.o.t emission regualtions and would a de-cat pipe cause me to fail my m.o.t? and also does anyone know the cost of a powerflow system single exit for the 1.4rt? thanks
Get rid of the cat. Its legal to run without one as long as your emissions are within limits which they probably are. And if not, you can only have the emissions tested at an MOT station by which time you can put the cat back on.
ive just fitted a remus twin oval backbox to my 1.2 16v, if i got it de-catted would it be too noisy running on motorways and would it make any difference to the performance, ive been quoted £60 at powerflow.
