This is the most badass exhaust setup I've found for our trucks

lol vid quality is crap i couldn't tell if that was a garbage disposal or a v8 haha. Sorry man get a better vid 
My setup is a bit unusual but i have OBX longtubes, 2.5 ID piping to hi flow OBX cats, then to a Y pipe and single in dual out borla muffler. Very weird combo but is the meanest sounding 5.4 IMO lol. It backfires, cracks, snarls and has all sorts of tone.
