exhaust on 4.6
Sounds like good comments for loud so far. If you use a muffler, buy a shorter one than you normally might. The multi-cat set up quiets them all down. For mufflers, try a short, stainless steel, straight through design.
I had my factory system cut out and dual straights put on. I absolutely loved the sound, but after a year of not having much grunt down low, I went with Magnaflow's 15609 catback system. I miss the sound a bit, but I love the power. A great compromise is a Magnaflow 18" SS muffler. I've heard it on a 4.6, and it sounds great . . . pretty aggressive but not overly droning at cruise.
