Rerouting exhaust to a low pressure point
I'm thinking of trying to reroute my exhaust to a low pressure point to reduce exhaust back pressure. If I route it to the back of the car in the slip stream it should also reduce drag slightly. As I see it I would get almost nothing but gains. Less back pressure, slightly more boost, and slightly less drag.
The only potential problem I see is diesel soot getting on the back of my car.
