Got the truck back from the exhaust shop. If you're in the New Orleans area, I recommend Custom Muffler in Kenner. They do very solid work, knowledgeable and they take great pride in their work.
I'll have to get pictures later but I got true 2.5" dual exhaust with a magnaflow 2 in 2 out muffler with a built in X-pipe and 4" tips at a 45. The truck has a noticeable change in performance over the factory exhaust.
