I have always wanted to do this just for the sake of goofiness and art...
Run the exhaust pipe, with flexible coupling, onto a long trailer..
so you are towing 15 feet of exhaust pipe behind you ..
with all emissions 'back there' ..
that way, no danger of turbulence sucking exhaust into the rear of the
van ..
which on a square-rear-end brick like a vanagon is a very strong
possibility.
And that is why the stock tail pipe is in the corner of the vehicle ..
so that a vortex there pulls exhaust away.
and ....we might notice some engine converters, even pro ones, never
allow for that in their exhaust design ...putting the tail pipe not out
on one corner of the rear of the van, as is stock from the factory in
all cases.
back to some I like to say in the Engine Conversion World
...........'do what the manufacturers do.'
and one thing they usually do is put the tail pipe at the rear corner of
the rig.
but hey ...put you tail pipe at the rear end of a longish trailer ..just
for fun, and to make a statement...'I don't mind polluting, I just don't
want to pollute where it bothers ME.' ( which is the basic problem
anyway, with humans. )
Being serious again...
I read about a case where an old ford pick-up drove on I-05 for hours,
to LA ..
when they got there, the two kids that were napping in the rear bed, in
a camper shell, were dead from carbon monoxide poisoning.
ANY leaks at the rear of a vehicle..
especially a box-shaped one, can be very hazardous.
