Go for a 3" dump pipe off the turbo then a 3" mandrel bent system back with a small free flow muffler to keep it legal in the noise department.
Steal or Stainless is your choice as this will effect price.

How much did your system cost you Dingo? Im going to have to fit a new exhaust as part of the engine swap in my LN106, and It pretty much runs where yours does.

When I done my one a bit of thought went into it and a few recomendations were made by mechanics not exhaust shop people.
On a 3.0L TD it was recomended that a 2 3/4" system from a 3" dump pipe back wold be best as the 2 1/2" would still be that little bit small.
The only problem with 2 3/4" is that a lot of exhaust places don't keep that size stuff on the shelf and don't have the dies for mandral bending so I went to 3" instead of droping back to 2 1/2.
I spent a little more than others have but happy at what I got, and service I got from the guy that done it. It has been made in 4 peices with flange joints so I can remove a piece if it is bent ect..
Dump to double braided stainless flex joint.
Back end of flex joint to beging of crossover
Crossover to begining of a 85% free flow muffler(keeps the DB's legal at full noise)
then from Muffler back to end
Also re-routed the system to make other things easier to service ect so there were new mounts to put in and modify others.
What insurance are you with as I have never had the problem of an insurance company knocking back an aftermarket exhaust system.

i got a new dumpipe made then 2 1/5 back with new flex and strait through muffler.. i am with racq and didnt effect me. the main thing is the dump pipe cos the factory are CRAP if you get the exhaust without it then all you are gaining is a cool sound and no power
