I'm trying to find out where these fumes are coming from. i have new exhaust and Ive had it checked for exhaust leaks no leaks. in the front seats you can smell it but in the back seat it is much stronger anyone has anyone had this problem.

Yes, it was from a partially missing trunk seal, and no package tray.

Flat portion inside the car, between the top of the back seat and the rear window.
