Flowmaster Muffler Questions
2004 F150 Lariat (New body style) 5.4 3V Engine
This is my son's truck. He wants to get a cat back exhaust into a Flowmaster muffler with duals out the back and 3.5" rolled tips.
Which muffler is the loudest, the Super 40 or the original 40? I have only used the original 40's on a few of my street rods in the past. I have no clue what the difference is between the two.
