one - it would need to be suitable for the amount of emissions you are releasing. A standard one should work fine if your engine hasn't been modded.

is it a full stainless system?

im not 100% shure but i think you only need one in the std manifold if its a face lift
and two for the pre face lift, one in th std manifold and the center cat

but moads people just replace the perfomance system with the std one for MOT's

its one to pass, depending onyour emissions

it's a full stainless up to the manifold then its a standard micra manifold that has been chopped and welded on.

i passed my mot with just the rear cat.

some people pass with one cat and some people dont...mine failed with the centre cat removed.

then it failed with the front cat removed, and centre cat in place.

so mine failed with only one cat in place.

here is a spanner for you lot then mine failed with both cats in place it all depends on the o2 sensor as thats is what was wrong with mine
