Exhaust routing. Long panhard and tailpipes?

[bigmoe]

My v8 engine and trans are sitting in my bare frame now. Planning out the exhaust. I have a curved up double hump trans crossmember and I put 4” pass threw pipes in my trailing arm crossmember. Plan is to run my pipes along the inside of the frame through the trailing arm crossmember. What have others done that have gone this route? Looks like it will have to curl inward and the dual chamber mufflers will have to sit between the arms and the driveshaft? Turned on their sides? Also I put a POL long panhard bar on the square body rear I put in my 65 frame. Looks to me like over the axle tailpipes are not an option now? 3" drop spindles and Wrangler springs in back for 4-5" rear drop.
