i know i've asked this question in another section but couldn't quite get an answer, if for example i have kpro with header, intake, exhaust, etc. Now after having a remap would that allow it to pass the mot? if not then it would obviously be a case of chucking the oem manifold and cat back on, but is this the general idea that everyone switches their header to oem just before mot ?? also, if that is the case, is it easy to load an oem default civic map for when the manifold and cat is on and easy enough to switch back to the map that i originally had for the header, intake, etc?
