RE: New Mega Cab Owner Needes Advice.
I replaced my muffler with the MBRP kit in my sig. It is quiet while going easy, and gets a good sound under load. The in cab noise is not a problem. I didn't notice any improvement or decline in HP or MPG from this mod, but it has to flow better, it is a straight through design. Not too expensive either, you won't catch me spending what they ask for the Aero.
