Have you thought about using oval tubing to go under the frame connectors??? I personally haven't done this, but I have been thinking about it for awhile. I like the look of the exhaust of the AAR Cuda's exiting in front of the rear tires.
This through Spintech, retail ,or Allied exhaust with a shop owner/buddy. A hungry fabrication man,could help you. The late model 4 x4 guys,are amazing.
