The headers are for the breathing with the 4bbl. The interior of my 292 is bone stock with about 33K miles on it. (Long story about the mileage)
The split manifolds and pipes run down under the cab as duals. I didn't want to cross under the truck with the right side pipe, and I preferred not to have the two exhaust pipes dumping together. Being a dually, there's a lot of open space, but I didn't want the exhaust pipes just hanging out either. The pipes came under the cab pretty close together and didn't leave a lot of room for a pair of mufflers, but one of the guys at the muffler shop came up with a muffler for something that had a 3" inlet, and two 2" outlets. I looked through the muffler from both ends and could see right straight through it. There was no indication of baffles either direction. I asked them to put it on backwards, so now the two 2" pipes from my duals go into one muffler and come out the one 3" end with a downturn behind the cab. The engine breaths well, there's no restrictions, and there's no obnoxious resonance in the cab at any RPM.
