That actually looks pretty good, in terms of layout.

What it takes up in additional weight, it likely gives back in ground clearance under the rear suspension compared to a larger diameter single pipe, in terms of cross section for flow volume being equal.

I wonder if a pre-made X-pipe could even be used, to really cross-equalize. The dual resonators look good.

It kind of makes me wonder if the Aero mufflers would sound good on the flat 6, in that sort of dual-muffler arrangement.

Although, my favorite sound that I have heard on sound clip videos so far has to be the stebro system, which someone captured at the Reading meet... That system is single run and muffler, with dual tips. Normal open flow sound at idle, and then an exotic-car scream at high revs...
