Just wanted to drop this in here. This is my car with the AA catted DPs, equal length midpipe, and the OEM valved muffler (valves open for the video). Also have the AA carbon tips which are so nice.

I know it's not what you're asking, but for continuity I'll include the info here. This was on my way home from having the AA valved rear section swapped back to the OEM one. The reason was just the cold start. It was so thunderous, like the precussion was tangible in your chest. Now with the OEM it's still just as loud up top, but when you're just cruising it feels like a luxury car again and less like a racecar. It also doesn't shake my entire apartment building when remote start the car in the morning.
Other than the ugly look of the OEM muffler, I think this is the ideal set up.
