I don't mind the old car smell, specifically the exhaust "fragrance" of early 911's. However when out cruising around, my wife complains about the strong exhaust odor in the car. "Roll the window down" didn't fly over too well.

I am going to inspect for the obvious, but I did replace the rear foam defrost tubes and poke around for the obvious. My car has a newer set of SSI exchangers which is what most of the "search" function shows.

Do any of you have a small checklist of items to verify? With summer fun-runs and shows coming up, I'd like to tackle this best I can.

Thank you for any insights!
