Thanks Jeff. My car was original as it can get. Built July 14, generator, 260 and it did not have a suppressor at all. Just looked at photos and there is isn't one there. The only thing i can think of is that it was a dealer installed radio, and the suppressor was never installed, at the point of purchase as "Radio" is on the original invoice. I do not know of any way to determine if it is factory or dealer installed.
