HPF exhaust vs. AA exhaust?

Currently stuck between the two!

Differences I've noticed:
-HPF is a single 3.5" pipe from the DP back to dual tips
-HPF uses a single 14" resonator
-HPF uses a flex section (which helps when the engine moves around)
-AA is a dual exhaust from the DP back
-AA uses an x-pipe
-AA uses dual mufflers at the rear


HPF is $1595
AA is $1890

Opinions and soundclips of AA and HPF exhausts on an N55 car would be greatly appreciated!
