My wife and I were on vacation in our '07 6.0, and I started smelling exhaust fumes in the cab. My motor was out and 'Bullet proofed' about 7 years and 50,000 miles ago. I did check the down pipe clamp and it was tight. Does the down pipe to turbo junction have an exhaust gasket?

If it doesn't have a gasket is there anywhere else that has caused exhaust leaks? I do have a parts list of the parts replaced and I don's see the up pipe there.
