exhaust on 4.6
#5
#6
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.
