I remember the pipes as a talking point when the Vanagon was introduced. I don't know much otherwise, as an air-cooled owner I see water as a corrosive agent that's best kept away from the motor. Look at what it does to the inside of tailpipes.

That's why I was thinking of replacing the decklid. Is it a low miles, matching numbers example?
A notchback body supposedly has counter-rotating vortexes coming of the roof that increase the pressure on the decklid. The rear-facing part of the lid is really small, but your exit could be between the taillights plus full width up to the wing.
There is probably a lot of structure behind the bumper, how would the air get to it. I do think it would look good to move the license plate up to between the taillights and have the whole bumper look like a front one. The profiles look similar. When you replace the front bumper with a blank piece, you could cut the center out of the old front and graft it into the rear.
