no significant power increase to speak of. any feeling of increase I get probably comes from the roaring sound. these 5.4's sound incredible with a good muffler. i recommend everyone at least get the muffler swapped if for nothing else the satisfying sound.

You don't need no stinking exhaust. It's not that loud with a cutout right after the cat. Except at 2000 rpm, and then it rattles your brain!!!!
