I really liked my N/A with a 2.5" catback with no resonator and a Borla ProXS muffler. Very nice and deep, a bit of a bumble and none of that super farty $h!t all the jackasses with their 3.5" exhausts and coffee can mufflered Honda's think is so hot. Besides, too big and you'll take a performance hit. I still think I would have preferred a resonator to quiet it down further, but I went turbo before getting around to that and the turbo cut the noise down a ton.

The ideals are: as straight a run as possible (as few bends as you can manage, mandrel bends preferred), acute angles (avoid bends greater than 45 degrees like the plague), straight through resonator and muffler.

Of note too is that 7M's have a horrible drone around 2.5KRPM... a good resonator and muffler will help prevent this headache inducing nuisance.
