Hi Vance,

Thanks for the reply.

Normally I would agree with you about Vizard, however in this case he seems to 
leave some stones 
unturned.

For example, he points out that a Flowmaster will appear to the engine as the 
pipe end (no affect on 
flow), however a glass pack will appear as a longer collector pipe which does 
have an affect on 
pressure wave and can reduce power. He seems to say good things about the 
DynoMax Super Turbo, and 
it would appear he does not put in the the same category as a straight through 
glass pack, but he 
never actually says whether the DynoMax has the same characteristics as the 
Flowmaster in regard to 
  appearing to the engine as the pipe end.

He also talks about adding a resonator box to the system but never actually 
describes how to do it.

Maybe it would help if I had my Falcon Group 44 headers and collector pipe in 
hand to better 
understand what he is saying.

I guess I was left confused by his article. Perhaps exhaust systems are just 
too complicated.
