install dual exhaust on 99 dakota

I am installing a new exhaust with converter and then after muffler it goes to dual pipes, question is I am looking to keep fairly quiet and will be installing a resonator of some type and want to know if it should go in front of muffler ? Or should I get two resonators a put them behind muffler before the tips ?

There is no current exhaust it rusted off at the manifolds and was no tail pipe, but have purchased new y-pipe and cat. with stock style pipe and new muffler that has the dual pipes included , it would be a stock setup until the duals coming out the muffler but is a kit to fit the truck , I am adding Magnaflow Performance Exhaust 14616 Stainless Steel Muffler to use as a resonator because I dont want it to sound like a honda when accelerating . Which is why I was wondering before or after muffler
