Mike, I will send you directly the URL for a photographs I took today of the
tail pipe on my very low mileage 67, with factory single exhaust.
Unfortunately, my 68, which has dual exhaust, has had the exhaust system
replaced, so while it is close to the original in configuration, the shape
of the pipe end is not exactly like the original, nor is the resonator
exactly the same shape.
For those who don't want to download the pictures, perhaps a description
will suffice: The pipe ends about 1 foot in from the rear bumper, with a
turned down section of pipe which is just long enough so that the horizontal
cut line of the end of the pipe just misses the straight part of the pipe.
Very elegant, and absolutely impossible to see, unless you assume a very
un-Imperial stance behind the car and peer up under the rear end, which I am
sure no gentleman would ever do. It appears that no concern was evident
regarding the exhaust fumes finding their way into the car, even though the
exhaust is dumped almost under the middle of the trunk floor. Perhaps the
sealing of the trunk floor is so good that this was not an issue.
The 67 with original exhaust single system appears to be identical (except
for the absence of a left pipe) to the 68's replaced dual system, except
that the cutoff of the pipe is orthogonal to the pipe centerline of the
turned down section, making a poor cousin to the original, elegant angled
cutoff.
