Too funny Neil, and FWIW I think most people's opinion of what an original Model-A sounds like is not even correct. Many people used the Midas manufactured reproduction exhaust system during the 60s thru the 80s and they were different sounding. Even the Aries muffler compared to an original Ford-supplied exhaust has a slight sound difference, ...and the sound is even more skewed on today's engines because most engines that we have today have compression increases. A 5½:1 or 6:1 compression ratio head changes the sound over a 4¾:1 stock compression ratio. For the ones that don't believe me, be a spectator at a national event during Start & Idle, -or at the beginning of the Mandatory Tour and have a listen to the cars that are using an original Ford exhaust and have stock compression.
