Here's a rear view of the Tatra 603, showing the dual exhausts (just barely). I don't know if these were OEM, but they're appropriate for a V-8, obviously. The sound was what alerted me to get the photo, as the Tatra was driving away. To reiterate, though, the exhausts are very hard to see in this photo, and appear to be curved to the side, a feature that I don't remember. I thought I had a better photo.
