Im thinking of changing my exhaust from the 5' stacks to the 4" dual out the back with a bully dog craper mufflerwhat do u guys think...The 4" dual should flow nice Right? I am getting a non vgt turbo and i dont want it super loud and the stacks are super loud even compared to my old 5" out the back

no that should't be too restrictive. It will definitely be a lot quieter in the cab than the stacks but I think it will still sound really good and look pretty killer too. search for some exhaust clip vids on the tube to get an idea of sound.

you wont see a difference with or without a muffler performancewise. mine was not bad with a straight pipe and non vgt

I noticed about a 50* or so drop going from 5" duals to a 6" single.

Ya i like the way they looked on your ford last year when we were at thetrack...thats kinda what made me like duals on a diesel.

Well i will have my dual exhaust 2marro so we will see how it works out....I already sold the stacks to a buddy and we put them on his truck last night so im exhaustless Its loud as HELL!!!:doh:
