The quoted post above is from one of my posts, and I beg to differ with Hemiman - well somewhat. The engine described is my 292 with tubes and a 2-into-one, then two-out muffler. Sounds like a stock small (283 or 327), small block block with turbo mufflers. The exhaust note doesn't get "raspy" until you get to near the rpms limits of the engine (4k or so).
Nice low sound up through about 3k. Just like I wanted it. Could you tell the difference if I were parked next to a truck with a small block and tube headers. Absolutely! The small block would definitely be distinct. But it doesn't sound like your typical straight six. By far!
