I have/had MAC dumps.. I cut the dump tips off though and had a set of 3" flowmaster tails welded up. I've always had MAC mufflers on my stangs. Only 1 set of 2 chamber flows (on my red coupe but i bought them on there). I'm a big fan of MAC catbacks
Thats my exact combo with a pacesetter X-pipe.I like flows but the mac mufflers sound great without the drone and at cruise it is quieter.
