The only cars from the factory with dual exhaust were k codes and factory GTs (A and K codes only). Everything else was single exhaust. Dual exhaust requires reinforcements in the rear frame rails and the rear seat pans. More than likely your exhaust was added by a previous owner.
Jim,I think you will want to edit the dates you posted. You meant to type 1965 and 3/25/65!!!"In early 1964 (3/25/64) Mustangs got a different dual exhaust system (previously it was an Arvinode Dual Exhaust System) for cars with the HP engine."Seeing that his car has a scheduled date of 8/10/64, a true dual exhaust car for that date would have received the transverse muffler dual exhaust system.
My VIN: 5F07A25010Build codes: 65A R 29 11H 35 1 6 (Aug 11 1964 Dearborn scheduled build date)I removed the rear seat, here are the photos. I didn't see either of the tell-tales that were shown in Ron's photo, but maybe my photos are of the wrong area? I didn't take a photo of the tunnel.Can someone review the photos and comment please?
Your car never came with a dual exhaust system from the factory. Do the "stick your finger in the rear frame rail" test to prove that to yourself. That is the easiest "test". Jim
