I posted my actual facts with a very good header system, 4" head pipes and Walker Mufflers.
Bigger head pipes buy you little when the cork is the mufflers.
When I was a National Tech Inspector for the SCCA we tuned for noise restrictions but still keeping as much performance as we could in the Muffler design.
