I did car stereo for a long time as a kid and it was always fun figuring out what worked for gain and what did not. I put two subs in the sidewalls of a toyota once (one on each side, pointed at each other) and they cancelled until you opened the trunk, then they complimented.

My mufflers are back just behind the cab, with dumps on the outlet it was horrible at low rpms. At idle the bed sides vibrated but droning went away at about 2k rpms. It does not do it now with full exhaust. There are a lot of bends to route the tail pipes over the diff and around the fuel tank. I assume the turns influence the sound waves as well.
