Paul,
The 68 Hemi S/S cars did have mufflers - they were kind of like glasspacks. From what I am told, in S/S, you had to have the exhaust on the car - not necessarily hooked up - that is why you see the exhaust under the cars - the racers slipped the pipes off the headers and wired them uo to the T-bar mount.
