With cat-back OFF. the pipe ends at the hand brake lever
video doesnt do it justice. I drove to a RR day and clocked 151mph with no exhaust. even with ear plugs my headache lasted 2days and I could feel my clothes vibrating.

looking good mate , you got the transfer box adaptor sorted yet? or you designing as you go?
The rear wheel prop drive of autobox can be removed for a 4x4 conversion I posted a link to guy in Zimbabwe who used 2 19mm plates,section of tube and bracing plates.
I'm not convinced this is the best way as he mentioned custom propshafts and that hints that prop angles will be more acute.
i read a bit more in some of the links you posted,as i'm sure you did,and one guy said the transfer box only moved 35mm.(i'm assuming he was dropping the engine and box into a standard drive train) wouldn't think that would affect angle too much and you can do your own props. would suggest (not trying to teach my granny how to suck eggs) working forward from the transfer if using one of his adaptors and moving/modifying engine mounts to suit. very interesting option.
