Axle-back parts have pretty similar sound characteristics between each other since you're changing a small section of piping that essentially just controls volume. As for a full cat-back, low-end changes will hardly be noticeable if at all unless you get something >2.5" piping (don't). You can also disconnect your battery during install to reset the ECU and help it learn the change quicker.
Only thing I disagree with there is that the Motordyne drone is almost nonexistent in my opinion. Meanwhile, the AAM short tails do have a moderate amount of drone from my experience.
