It's clearly beneficial in a dual setup for eliminating drone/rasp and increasing performance but we don't have a full dual set up. In any case, even with an x pipe in stead of the resonator it still needs to go into a y if the stock muffler is being used. If you have a dual inlet muffler like a magnaflow or a flowmaster then it changes the game, but my plans involve the stock muffler.
