1965 Formula S 5800 miles

Great video......and we heard the legit sound of an early straight through muffler. All 65 Formula S cars did not sound the same. The early versions were much louder and had a signature snap, crackle and pop when decelerating.
Thanks for sharing

So...are you inferring there was only one muffler (I assume the special rear resonator) on early '65 F/S cars? If so, I would like know more, because I am restoring an "early" car build date 12-14-1964, and the parts book clearly shows two mufflers, two part numbers, in the breakout for all '65 with 4bbl Power Pack 273. Clarify please, if you can.
