Exhaust Pipe Sizing - Help

I have a 1972 chevy nova street muscle car. It needs a new exhaust system. It has a 550 HP Big Block Chevy. The headers have 3-1/2" collectors.

Should I go with an X-pipe type system or just standard dual exhaust or doesnt it matter?

What size exhaust pipes should I use? 2-1/2", 3", 3-1/2"?

I would like some free flowing mufflers that are loud. Can you recommend any particular make or model?
