Default 2 mufflers or dual in dual out muffler

I have the dual in and out but wonder if the 2 mufflers will make more power? any thoughts?

I have read somewhere that 2 mufflers makes it sound better, but I doubt it does much for performance.

Thats why I am going to go with 2 mufflers when I go duals on my truck.

my dual/dual is a bit farty/glasspack/hick truck sounding between 1700 and 2500 rpm. running the pipes all the way out helped alot and it is now quiet. does the 2 muffler setup sound deeper? and did you run 5x8 or 4x9 and what length?

I have Magnaflow's dual 2.5 in dual 2.5 out 22'' long muffler turned down before the rear and with stock cats in my opinion its perfect. it doesnt seem to even improve my e/t when I open the cut outs.

my dual/dual setup sounded like that to and the doubles are probably worse but not redneck the doubles are deeper but i have no cats so its pretty loud.
