umm.. between the two i would say get the borla non rez.. becuase i will fight to the death that it is the best sounding exhuast that trubendz makes.
flowmaster in general is just a, eh... crappy sound.
i hear that the mag flow is just too mellow.
borla exhausts have known to be hands down one of the greatest companies. .. um yea,
borla non rez
