To preface, I would grade my exhaust knowledge with a "B-". I know what the major components are and what they do, but I don't know if and when certain exhaust parts became mandated or introduced over time.
I love how a throaty late-60's/early-70's muscle car exhaust sounds. Gnarly, a bit raspy, yet throaty and with some oomph. But when I hear most current muscle cars - 90s and on - the exhaust is mostly deep and loud, with little of the raw or explosive sound that the classic cars have. The classic muscle cars sound very similar to an inboard/outboard boat engine, where the contemporary muscle cars rarely achieve that note.
A few examples to describe what I notice... (site won't let me post more than 2 links, I posted the most representative examples of what I'm describing)
- I understand straight pipes make it louder
- I understand bigger cams stagger the rhythm of the revolutions
Is there anything inherent that causes the discrepancy in exhaust note? Or do modern manufacturers and modern aftermarket performance companies prefer the "newer" sound?
