Re: Single vs dual exhaust -- Vizard and mufflers

This leads back to the thread about ceramic coating the inside of headers and 
as far back as you can go on your exhaust system.  It reduces turbulence and 
drag on the gas flow, thus increasing velocity and improving cylinder 
scavenging which in turn increases the air/fuel "charge". 

I've dealt with APT on a number of occasions.  Very nice, helpful, former 
(current?) racers with high end products, especially for engines.  Their 
website is aptfast.com
