2009 6.8 dual exhaust

I just removed my Banks system and had a 2 1/2" dual system built. I was sick of the noise between 1600 and 1800 RPM when I was towing, it had a droning sound that was driving me crazy. I called banks and expressed my feeling but you know where that went. So after rethinking the exhaust and looking on the market they all seem to be the same but with a different muffler. So what I did was start out and remove the y pipe just after the converters and run two 2 1/2" pipes into Magnaflow mufflers and then into the banks 3 1/2" tail pipe using a y adapter with dual 2 1/2" inlets and a 3 1/2"outlet. The y that is just after the converters is very restricted, the pipe's are bent a little over half way shut to make that up. The bottom line is the truck makes more power and right off idle it is must better, and the best part is it is very quiet. I would go this way over the big single exhaust if anyone is thinking of adding a exhaust to there truck
