Exhausted. Would like your input.
I'm using a TMeyer 400 rebuild kit and plan on using some nice long tube headers. My question is would it be best for torque to run true dual exhaust or a free flowing two into one setup? I am planning on a passenger side exit right behind the cab, mainly to keep the exhaust away from the fuel tanks.

Excellent question. Everything I've read says that you need a crossover not too far after the exits of the headers to help the flow. After that I don't think it matters much whether you have duals or single as long as the system flows the same - but that is a guess.
What headers are you planning to use?

I have had both true dual and currently have a two in to one setup. The hell with the true dual setup. My setup is a 2.5" dual in to one muffler and a 3" single tailpipe that exists in front of the right rear tire. Makes gobs more power and torque over the 2.5" true dual short system I had.

My understanding with crossovers is that any form is better than none, most exhaust work I've seen for the past 5 years or so has used an "x" pipe instead of the old style right angle pipe cross feed.
I Have seen an exhaust shop show the way to find the optimum position for the crossover, they drew a thick line along both pipes from the collector back with a wax crayon. Note the full twin system was in place apart from the crossover. They then ran the engine to get the pipes hot and at the hottest place the wax melted off, this is where they placed the crossover.
Personally I'm a fan of big single systems for lots of reasons.

I am not a fan of true duals on trucks, especially these trucks. I've had experience with two vehicles with two in to one systems, and both were positive experiences. I've found that a two in to one muffler also helps reduce inside the cab resonating. Although I have a magnaflow style muffler, so I barely hear anything inside the cab.

I like the sound of duals exiting on opposite sides - even the single inlet/dual outlet Magnaflow that's on Rusty. But, if the exit location is in the same place then I'd go with a single.

I'm going to go with the single tip option, simply because this is the best argument. Now I have to find a dual inlet, single out muffler that is not too restrictive.

It lists it at 3" inlet 2.5" outlet but they're reversible. Fully open inside.
Here's my truck with a Magnaflow style muffler with the same size pipes. I love it!
