With the emphasis on "correct". If the plumbing is too small, letting 
the exhaust cool a bit could help because the volume will contract. SO: 
too big = too slow velocity; too small = restrictive.

Why would the high RPM engines not benefit as well? They sure go to a 
lot of trouble to "tune" the pipe lengths, so it cannot be said that 
extraction effects are meaningless. And if I were an engine designer I'd 
SURE want those bright red pipes to keep their heat to themselves!
