Plus the hot air form cooling is also exited straight out the back, another
thing we don't want on the intake side of things. (vapor lock, poorer
cooling )
The exhaust fumes ernie is experiencing is most likely an exhaust leak
inside the lower shrouds. -- no donuts (6) for the manifolds?

I'd agree with Tim that the exhaust leak is probably inside the
shrouding--or because of gaps in the shrouding--especially the middle piece that covers
the harmonic balancer and rear engine mount. If you can smell it then it is
because of the oil vapors and combustion gas as the poisonous CO is odorless
by itself. But, even with the longer trombones I once ran on my Corsa (and I
did like them) there was exhaust that was pulled back into the heater,
turning my paper CO detectors a different hue and those were securely mounted to
the engine and not the body so my packing stayed tight. All Corsas and Spyders
that I saw when they were new had the exhaust turned to the side about 45
degrees to put it into the side stream when the car was in motion. And I
believe the assembly manuals specified this as well (haven't looked at mine yet,
but I will to verify). If Ernie has his Flowmasters securely mounted to the
engine (not body), all shrouding sealed and no heater hose leaks he should be
able to enjoy them--but keep the vent window open.
