Default True Dual Exhaust size for 455 cu.in. 600+ FW HP?

All-
What should the pipe size be used for true duals on a 455 cu.in with 600+ Flywheel hp? Would true duals with x-pipe 2 1/2" be acceptable?
I want to run all the way back.
Bassani makes a great 2 1/2" system. But 3" is not out there.

3.5" Piping DUMPED.

Or

3" IF YOU WANT ALL THE WAY OUT THE BACK.

I would say you need at least 3" true duals

I ran 3" straight back to dumped turbo mufflers when I had my Olds running. I know it probably wasn't the best for all out performance, but the sound it made with a big cam was sick. I still have that motor...You'll probably have to piece one together to run out the back, 3" should be sufficient though with decent mufflers.

3" would be the minimum I'd go with. You might want to even go 3.5".
