Do Heads=Louder Exhaust??
it would make some sence. the way i look at it the more hp you gain the bigger explosion you have in the cc which in theory it should be louder. dont know if it's true or not be it sounds good to me
i wouldn't think it'd up the exhaust note too much, the cam has much more effect on the exhaust note(ie lope, duration, et cetera). if anything you're talking about larger open spaces, internal resonance, but since there is gas/vapor mixes swirling around in there its pretty much a moot point.
this is honestly the first time i ever remember even considering this....i don't think i've ever heard anyone bring this up before. am interested in the replies.

one thing they mentioned that surprised them was how the exhaust note
changed in both db & tone.. said the low comp sounded wimpy and the higher
comp's were sharper w/ more of an authoritative note..

My exhaust note seemed to be throatier and deeper after adding my heads. Whether this was due to higher compression or better flowing heads I don't know. I also noticed the same thing when I installed my AFR 195s on my 360Ci Marine Engine.
