i had got told something like that by a mate of mine but thought he was just taking the p:c

does it make much difference if you remove the cat then?

think it was petrol vehicles had to be manufactured with cats from 93. but i think no vehicles by law have to have a cat as long as they can meet the emisions applicable to their year. but as said above the emmisions for deisels are differentT:

i've got a 2.5tdi, seems to make a bit of difference since the de-cat.

i went from a full 2.5tdi standard system with cat fitted on my 1.9td to a full stainless 2.1/2" powerflow exhaust with no noticeable difference , ok maybe slight improvement
