2002 - No More Turbos

I seem to recall an article on SAAB's trionic engine management system that
had intake air, to car #1 (some SAAB), coming from the exhaust of another
car, #2, (I think it was another SAAB), the end result is that the emissions
from car #1 ended up cleaner (in many respects) than the exhaust form car
#2. I do however forget it whether car had a turbolader? Anyone remember
what I'm talking about or am I talking out of my gluteus?
