Im about to get a remap, i have a downpipe and 2nd decat ready to go on the car before the remap, when mot time comes im planning on putting the original down pipe back on for it, will the emissions and everything be ok as it is mapped for the decat downpipe orrrr???

I would get a 100cell downpipe but i just cant afford it with everything else just now, or should i keep original downpipe and just get the car remapped with the 2nd decat in.
