I pretty much took off my mufflers for the night and drove around. I compared the sound to a guy with 2-chamber flows and it's definitely the sound I'm looking for. The flows and "straight pipes" are pretty much identical in sound except that it's more smoother sounding above the 3500 mark. Time to take off the dynomax's and get some flows.
I like the MAC catback almost as much as I like flows. The MAC catback sounds awesome now. Now you just need to get rid of that High flow H-pipe and get the MAC O/R H-pipe.
The only thing that I have against Flows is that they have become the Cobra R wheels of exhaust. We all remember a few years ago when every other Mustang had Cobra R wheels. Don't get me wrong, Flows sound nice but let's have some variety. MACs are quite nice
