Hi Doc,

was looking for Cyclone Sonic Turbo on the web and found this article 
http://www.nsxprime.com/FAQ/Miscellaneous/exhausttheory.htm

Excerpt....
According to the flowbench, two of the best flowing units you can buy 
are the Walker Dyno Max and the Cyclone Sonic. They even slightly out 
flow the straight through designs from HKS and GReddy BL series. Amongst 
the worst, are the Thrush Turbo and Flow Master mufflers. We'll flow 
some of the newer mufflers as they become available at our local Chief 
auto.

Lots of opinions out there I guess...

I would like good flow, not excessively load (annoyingly load? 
subjective I know) and would like it to sound something like a 
Triumph... I'm open to suggestions.

I've ordered Falcon headers from TRF. I think they use 2.25" pipe. I 
assume I should use that all the way back. Kas says a single 2.5" pipe 
is best but he was probably spending a lot more time at 6K than I will be.

The cam is 274 duration, 222 @ .050", .426 valve lift, lobe angle 110. 
The head will be at 9.5:1 CR, oversized valves, 3 angle I hope, and mild 
porting (Per Kas). Bottom end balanced. I have been told the dual ZS and 
stock headers will not keep up with this head -- thus the Falcon Headers.

Any opinions of Cyclone Sonic or DynoMax? Vizard recommends Cyclone 
Sonic in his "Tuning the A series engine". He recommends Dyno Max in 
another book.

Thanks,

Don Malling
