Alright so here's the deal. I have a 2012 4x4 quad cab express (5.7) with factory duals and I want to upgrade my exhaust. I really like the metal mulisha/Gibson exhaust but they don't make a dual version for it :'( So I was thinking about trying to order two of the MM/Gibson tips and whatever muffler that they use for that system, along with a magnaflow Y pipe. What do y'all think of the idea? Stupid or genius? Also does anyone know the size of the factory tubing??
Thanks in advance!
Below is the exhaust but not in duals
