(2) 71 GTX's, both original H-pipes still intact. I've sold one already, but still have the other. So yes, 71 440 cars had H-pipes. Maybe some didn't. Would be interesting see some others. There is a 71 GTX 10k mile V-code car thats fairly well known, Autumn Bronze Metallic, and another one, Hemi orange & yellow V-code, done by Roger Gibson (was in Wellborn Collection), that was a concourse cars.
