Yep Hank, you sure did. I even purchased a paper on line from SAE (Society of Automotive Engineers) that looked promising on exhaust tuning tests for a Honda 600 cc engine. Interesting article by some engineering students, but not exactly applicable to our discussion. I have the often referred to book "Scientific Design of Intake and Exhaust Systems" written by Philips back in the early 1960's. It's fine for what it is, but I wouldn't necessarily recommend others purchasing it. I don't know of any great books on exhaust systems.
