I have a 3" system on the blown beast that is "just a tad" loud at full noise. I haven't been arrested yet but I'd like to quieten it down a bit without choking it too much. It also has a booming harmonic (like a light aeroplane) at around 2400rpm which is a pain in the ears under any sort of load at freeway speeds. Nearly drove me spare during a recent trip to Warrnambool as the road between Newie and Melbourne is almost all 110km/h.
I understand that I'd have much more of a choice of quieter mufflers in the 2" - 2.25" range, and that systems like on the XR6T run mufflers that have twin 2.25" inlets and outlets. But the BA floorpan is apparently different and allows room for bigger mufflers. Has anyone tried fitting a full twin 2" or 2.25" system under an AU? My Paceys have been modded with a 3" collector and my cat has 3" in/out, so I'd be looking to Y out behind the cat.

Its easy, but you HAVE to heatshield the plastic AU Fuel tank right around so it doesn't melt
and it is possible.. easier in a wagon due to the old cart leaf springs

It doesn't have to be symmetric. I'd be happy to have both pipes go to the right side with dual tips on the right.

oh sorry, i couldn't read the OP properly..
yeah, its quite easy on a wagon due to the space (as above) and if you wanted to, you could even run twins out the back of each side (even if it means a single 2.25" to either side then 2.25" single in to 2.5" dual chrome out on either side) it would look good, and give better airflow as far as i can see
