The setup i currantly have on my car is the standard manifold decatt then my sports back box

Im looking into gettin a 4 2 1 off my m8 for £80 but hes saying rather than have it stright threw i should have my 4 2 1 a powerflow middle box then my decatt then my back box hes saying i need a middle box because the micra works on back preasure is this true or am i best sticking to 4 2 1 and decatt for the best performance or stick the middle box in ?? Please help

Thanks in advance !
 
it will be fine without a middle box...if you loose to much back presurre just put your standard cat back in..but i dont think you will need it.
 
yearh £80 is about right for a used one...you will know when you loose back presurre..just try going up a hill, it will be worse at pulling than standard. but it should be fine. TBH i would fit the standard cat but thats me. it will sound loud and raspy with the de-cat & 4branch manifold inplace.
