I have a Mk4 Golf TDI that I use almost entirely as a courier vehicle -- so much so that I have removed the front passenger seat. The rear seats are folded flat and they and the hatch area are covered with 1/2" plywood so I can haul more cargo. A lot of my deliveries are electrical, plumbing, HVAC and other parts and supplies for contractors. Generally it works out very well, because if what needs to be transported is more than my Golf can handle, we have other drivers with pickups, vans, and box trucks. I typically drive about 5000 miles a month.
Often I need to haul bundles of 10' PVC pipe, copper or galvanized conduit, or threaded rod. With the front seat removed, I can get about 9' of these pieces inside the vehicle, with about 1' sticking out the back. I use a bungee cord to hold the hatch down, strapping it to the tow bar.
Fumes sometimes get sucked into the cabin, so I have to crank up the fan and lower the front windows. But with winter coming on, I'd prefer to keep those windows up. So my question is, where should I reroute the exhaust pipe to prevent the exhaust fumes from entering the cabin?
My options seem to be 1) to the side, exiting behind the rear wheel, or 2) extending the pipe several inches straight out the back. But which is more likely to work? and if I extend the pipe, how far?
Other than trial and error, how should I determine which option is most likely to work?
