You're probably correct, but the existing Hushpower II ha= s no innards left.  It is a straight through chamber.  With a fla= shlight, you can see all the way up into the manifold.  So, I figure t= hat almost anything would be an improvement from what I'm running now.&= nbsp; Stay tuned...

I'm going out to the airport this mornin= g to see=20 how well it fits.  More on how well it fits & works later...=20
