Now tro a Flowmaster dual exhaust onto 'er, a programmer onto 'er, and a K&N air kit onto 'er and you'll be downright ready ta rumble. Oh yeah, and Rhino line that bed. Don't do no stinking bed liner!
I'm putting a Flowmaster muffler on my wife's Sierra 5.3. My buddy left his single and I think it sounds better than dual. Some dual have a tendency to "cackle" which IMHO sounds terrible.
I put an Edelbrock catback system on my Silverado and the only time you really hear it is when your in the gas
A little growl is fine, but other than that, I don't want to hear it. I only want the benefit of added HP!!!!
I'm looking at a 2003 F150 with the 5.4 Triton right now. If I get it, that would be one of the first things I did, to put on a Flowmaster dual and K&N. Then eventually a programmer.
