I am picking up a afterburner vortex for my97 classic soon it is a full system. I just not too sure wat to do?? I have a decat pipe up front and obviously I ll be fitting the back box . Do I change the mid section as well? I have a standard mid section at the moment and was thinking of just fitting the back box . How loud will it be ? Does it matter if I leave the standard mid section in or shud I change it at the same time??
