For what it's worth I went with the set up noted in my signature and love it. I also had an idiot at a national chain shop tell me it was impossible to run true duals on my truck. I laughed in his face and found a local exhaust shop that worked with me to design the system I wanted. It has made quite a difference in both the performance and sound of my truck.
