Seeking Exhaust Advice

I'm not familiar with the sbm hooker fenderwell headers. Do the collectors dump pointed at the ground, or do they curve around to parallel the rocker panel?
The most simple exhaust with fw headers is a short piece of pipe off the collector and a muffler running along the rocker, with either a turn down or a turn out. (In front of the rear tire). That's what I have on my fw car. The sound isn't great, you only hear half of the V8 pulses.
Simpler and lighter than curling it under the car, and then a tailpipe to the bumper.

(But I agree with AJ. I think the exhaust header-back on my 62 weighs about a hundred pounds.)
