What is the consensus for a dual exhaust setup on a stovebolt street machine? That is... what size pipes to use? Is it necessary to run x pipes to equalize? I was planning on using 2 1/2 inch pipes... same as the headers, but I am leaning towards 2 inch pipes now.

Aplication will be a 302 in a 1940 gmc.

I am also interested in how a setup should look... staight out the back, before the rear wheels, after the rear wheels, etc.

Any tips and links would be appreciated.
