Personal Prefference I think. Nothing major besides surround sound and side. I had duals MBRP on my last ford and went single on this one cause I like it being less bulkey. 2 pipes made no sence if it only split over the axle.
I like my single and don't for a minute wish I had dauls.. I jsut want a nice 6" single stack now..
You'llb e hearing from me Husker

The difference is all cosmetic, maybe a little sound as well. The duals do have a shorter muffler and the sound is spread out so they are a little louder than the single kit. The 4" single will give you all the EGT drop and power gain you can get from an exhaust though. If you would like a quote on one, shoot me a PM.
