Attention: TDR Forum Junkies 
I am trying to figure out what exhaust I want to get for my truck. I original plan was a 5" single system brand yet to be figured out. Well then I happen to see that MBRP make a dual system, but I believe it is all 4" pipe, I would have like to have 5" up to the muffler. Being a hard core big block guy I like the looks of the duals.
But the question is which will give the best performance and lowest EGT numbers?
