<VV> SPECULATION on 64 exhaust

[N2VZD at aol.com]

I would be thinking along the lines of the 164 cu inch motors breathing a  
little better , so needed better \ quieter muffler with more flow capability 
 ?
Just wondering...
In my sordid past , I did some exhaust changes that increased performance  
that you could feel , JUST by changing to a better flow muffler..
But that is a science of "intake / output" balancing...such as adding jet  
size with modifications to ignition timing curves and exhaust flow to  
match..
