Is My Cuda Killing Me?

I will assume you have full length tailpipes, if not that is part of the problem.

Do you have all the body plugs in? Should have about 6 in the trunk floor.

Also look at tuning, overly rich will make for a stinky car.

Believe it or not, "full length tailpipes" will not cure the problem. If the trunk lid / trunk floor has leaks, it can STILL suck fumes under/ into the car. A badly leaking/ missing trunk seal is classic example
