Default Gen1 Cat-Back muffler

The in-cabin noise is ok-ish even though even with the Cobb hangars the mid resonator wants to touch the chassis a little which has an unpleasant impact on the cabin comfort, but with that pretty much addressed (when it gets too close I adjust it) I'm now after lowering the outside noise levels a bit as well as the noise the rear passengers get.

So did anyone fit a muffler to the gen1 Cobb cat-back and can share the dimensions? I'm debating between either fitting a small muffler there (the largest that can fit) or even a catalytic converter which should also tame down the noise a bit. I'm open to suggestions as well, anything else than "leave it as is", simply because the regulations will become stricter over night, probably some politicians are tired of hearing their children complaints about being smashed in their lamborghinis and ferraris every day in night illegal races by small turbocharged hatchbacks.
