What does it take for a modern muscle car to sound like a classic muscle car?

It has very little to do with the exhaust system and much to do with the mechanics of the engine. All modern muscle cars have aluminium blocks (vs cast iron), round exhaust ports (vs rectangle), and completely different timing set ups than 60s cars have. The firing order makes a big difference because nobody fires 2 in a row on the same side of the engine anymore. Thus engines have much better balance now and are smoother sounding. It's also one of the reasons red lines are so much higher. The thin walled aluminium blocks and heads resonates sound much differently than cast iron did and even things like 6 bolt mains change engine resonance through the block giving you a tighter tinny sound. Of course just like air blowing over valves in a trumpet the shape of the combustion chambers and round exhaust ports changes the exhaust note too. In short the only way to get the 60s sound is with a 60s car. For what it's worth I have tried nearly everything to get my LS1 Miata to sound like a rea
