Exhaust/muffler questions?

[Touchdown67]

Okay I'm getting ready to have a new exhaust system made for my 1965 LWB fleet side and was wondering what brand or style of mufflers to run? Chevy small block 400 with stock ram horns. I like the look of duel pipes and would like to keep the rumble to a minimum. I am trying to maintain a semi stock look and sound. Flowmaster or Magnaflow 2.25, 2.5, or 3 inch? Crossover? If anyone has input or images of a good sounding system please let me know. Thanks....…
