I think a lot of the noise can be reduced by adding a few bends to your system. I have a set of Raptors (similar to Flowmaster) on my 93' 4x4, the exhaust exits in front of the rear wheel on the passenger side. I don't consider it to be loud as I can hear the radio or carry on a conversation... Flowmasters are a great performance muffler, they are load by design compared to a Turbo or Glasspack style.

Growing up my Father had a 70 GMC with 2 1/4 inch corvette mufflers that exited just in front of the rear wheels. It was deep and throaty it had a mellow tone at speed, never seemed overly load or obnoxious.
