I learned to live with it. A tune might help but I doubt it would eliminate the problem. "Better" cats might help but that sounds restrictive and expensive.

Thanx Southark,
But that would exit the tailpipes, correct? How would that get into the heating ducts?

I do have past experience with exhaust fumes entering the cab of a different car. These are NOT exhaust fumes.
They do not smell like exhaust fumes. They don't affect your eyes or throat like exhaust fumes do.
(But they ARE annoying to have in a NEW car that surely doesn't need a tune up yet)

Hopefully I will get a chance to check it on recirc later this week.
