Doing exhaust crossover tomorrow - Advice?

Tomorrow I'm going to have a muffler shop nearby that gets good reviews from classic car and hot rod folks redo the exhaust crossover to be behind the transfer case instead of under it. I still can't fathom why Toyota makes that crossover pipe the lowest thing on the whole dang truck when there is plenty of space behind the transfer...

Anywho, anything I should watch out for? Something I should point out to the guys doing the work?

I know there is some cabling on the back of the transfer I may need to protect with a heat shield depending on the routing. Presume I don't want the crossover to far back or I may get interference with the driveshaft at maximum droop?

 

How did it turn out I have a pipe bomb exhaust and can't get any closer but put header wrap on the pipe..

 

I wrote up the results in my build thread, here's a link to the post:
