I just got my first truck and it's a 2001 F150 supercrew with the 4.6L. I can't wait to replace the stock muffler with a glasspack. I'm not a welder so does anyone know the right pack that will fit where the muffler is now without fabricating additional piping. (what the inlet/outlet is, length, and angle if necessary) I was thinking cherry bomb but am open to any suggestions.
