Could it be Heinz that you still have the suction effect on the 4/4 but as the catalytic converter is working properly you just don't smell it. All my later (after 2000) mogs definitely suffer from this. I could always smell the exhaust for the first 100 yards until the cat warmed up and got working.
On one car I fitted a side exhaust which seemed to solve it.
On my roadster I decided to fit a wind block. I had several tries using the headrest support but was never happy with the fact that seatback adjustment became difficult and there was a nagging safety worry with brackets just behind my neck.
At the time I owned a BMW mini cooper convertible and it came with a folding wind block. Very neat it folded into a quarter of its double size. I applied it to the mog (which had the new easyfit hood) and it fitted well. Because it folded lengthwise if I set the upright part against the headrests the back part hinged and worked as a brilliant parcel shelf cover, disappearing into the folded hood and stopping anything flying off the parcel shelf. At the sides it had two rubber spring loaded prongs to fit into recesses in the mini design. I simply drilled two small holes in the wooden side rail of the easyfit hood, the prongs located there and it all looked entirely professional.
Well worth investigating if you really need a wind block
