Im running headers, true duals, flowmaster delta 50's and come out behind the tire.

2 1/4" at the moment, but I have a full set of the same in 2 1/2" sitting in my garage waiting to go under it.

I don't experience any real issues with my flows, other then the delta ones are a little rattly. The 50's are to quiet for me, so the new setup has 40's again.

I am also running center in, center out. Those mufflers are little, so shouldn't really matter much for your application. Mine are hung from the factory spots on the crossmember right at the back of the cab, and again back by the springs.
