I had an exhaust shop route the passenger side pipe down and under/across the oil pan hump, alongside the driver side pipe for a short run, then a 2 into 1 to a nice Magnaflow muffler.
I'd do the oil pan hump if I were running manifolds, but with the headers, I'd be bringing the exhaust forward before I brought it across.
(Maybe tractor puller headers...)
How much lift do you have? I really wanted the 4spd behind the T19, but I got nervous about the rear driveshaft - and even now, I think I "need" 37-deg out of the rear 'shaft to keep what I had before.
(a HP swap is a long ways off)
With the 1" body lift, the belly will still be flat - even if I rotate the Atlas down to relieve the front driveline angles a bit.
Beyond formulating a plan, I haven't started in on the new crossmember yet. I burned down my bandsaw and I'm swapping in a new motor first... so I can more readily cut the steel for the crossmember project.
