1st one of course your primary sensor needs to be plug and then secondary is gonna be short , so you gotta extend the wires for it to plug in the 2nd bung that goes way below under the car and also since you mention a DX hatch, your gonna need a EX cat or a high flo cat since the DX has that ridulous resctive Head/Cat manifold design.
