Rick,
Gary at Vintage Performance does something similar with a double crossover "X" configuration on his 289 slabside Cobra. When he revs the little dual carb 289 motor up it sounds like its running 16 little cylinders like an exotic mini italia v8 or something. The pipes exit the rear and tip slighly upward. It was too loud so he has 4 or six mufflers on it now as I recall. He's played with various exhaust configurations like this producing interesting and different sounds. His Silver slabby was sitting there next to Gordon's #52 USSRC Cobra and Gary's #49 BRE Datsun 240Z next to it in Cobra row at the reunion.
