You'll want 2" pipe minimum.
I have a shop make bolt together flanges, buy mandrel straight, 45deg, and 90deg pipe sections, buy a flex exhaust coupling, cut the ends off a Mercedes 300D muffler and weld one up when the vehicle is on the lift.
It is easy.
The only draw back is the process is time consuming.
The couplings are a triangle made of 1/4" steel with a 2.25" hole in the center. Each corner is rounded and there is a 3/8" X 16 tapped hole in each "corner" on one piece and a hole just large enough for a bolt on the other.
One side is welded to 1 pipe and the mating pipe and the flange bolts together.
Then you can make the whole system in pieces that bolt together, so you can remove sections to pull the transmission and so on.
