Fuel economy and dual exhaust
#1

I just bought a 2001 2500 4x4 5.9L and it needs an exhaust (single exhaust out the side now). Would it be beneficial to go with dual pipes from the muffler back to aid fuel economy, I will be installing an electric fan, and cai, along with a tuner eventually. Will a cat back dual exhaust fit?

let her breathe a little a more with an intake an headers and itll sound a lot faster... i used to hear that same thing though that allowing the motor to breathe and exhaust better would not only net you a little more hp but a tiny increase in fuel economy...guess its just another myth.
