Thanks guys for the kind words. I always loved the tone of side pipes with a healthy displacement and thought, why not? There just basic Hooker 4" pipes with big block slip in mufflers for a mid 60s Vette appl.
They sound so good.
Only thing that was really custom were the intermediate pipes between the header collectors and the side pipes.
The exhaust shop couldn't bend 4", so I got a Hooker 4" 'U' pipe from Summit, cut it in half, and they provided the 90 deg turn & added length I needed. Pretty cut n dry.
It beats trying to find room by the pan hard bar !
