I am getting close to the point where I can install the exhaust system on my V8 powered 54. I have some ceramic coated block huggers that were given me but the rest of the system is up in the air.
What diameter pipe should I consider using?

What brand of muffler would be recommended other than flowmaster/dynomax/magnaflow, that would give good tone without [censored] off the neighbors? No fart can suggestions please.
