Default Exhaust size for 350 with 375-400 HP

On a 73 with a 350 making somewhere between 375 to 400 HP, what diameter exhaust pipes do I need? And is that using a stock muffler or a performance muffler. Not looking for loud but more of a quality sound. thanks for your help and suggestions!!

If you want to keep sound levels in check, stick with a 2 1/2" exhaust with good flowing performance mufflers.
