how do i remove catalic convertor from my frontera?

As t said but your asking for trouble..your ECU won't run properly you will have no oxygen sensor reading and a good chance of blowing engine due to over heating. And being fitted as standered t again rightly said you got no hope in passing a MOT. Why do away with it anyway? replacements a cheap these days can even get second hand ones if you look around and will be alot cheaper than a blown engine.

You just remove it and replace it with a suitable piece of pipe. More to the point how will you tell the car's ECU that you have done it and how will your car pass it's MOT?
