Exhaust Sizing Question

This is in general sizing standards the technical specs will be factired in later. I am wondering what size of piping to run in this scenario. Stock setup from header back is : 2.5" piping all the way. Two feet from header to catalytic converter 2 feet to resonator foot and a half to muffler then 4 feet piping with one main bend over axle. I want to run from header only five to six feet right before axle using only piping and one muffler but still want to run enough pressure. The cat is a normal size one and resonator is maybe 2" around bigger. Would running 2.5 from header to 3.5" to muffker and a bend for side exit so it doesnt blow directly on the axle give enough pressure allowing both out going and being sent back? This is in general theory to help decide to go that route or duplicate this route with seperate collectors to run dual.
