Bob,
You might profit from my mistakes. I did what you are planning and dumped the pipes out on the sides using Chevelle tips. The look is the only thing I got right. Please modify your crossmember under the trans as I didn't. Check out the street rod low profile mufflers which you can mount in FRONT of the rear axle. I installed the single muffler with multiple outlets/inlets as you described ... had to build/modify hangers, etc. ...never got decent sound and did get vibrations. But the Chevelle tips behind the wheels look good. They are all I plan to save.
