My 55 Belair 2dr Hdtp with sb has an exhaust smell in the passenger compartment says me and everyone that rides in it. I found several small leaks on engine like exhaust manifold to head and at the exhaust manifold donuts.Repaired those leaks and all holes in firewall, no help. The dual exhaust system, pipes and mufflers are solid. I am starting to think exhaust gases are entering through the trunk seal which is not snug especially near the tailpipe. The tailpipes extend about 2 inches from bumper. Also car has pcv so not blowby we are smelling. I was wondering if anyone has had similar problems. Thanks in advance for your comments.

You might try a set of turn down exhaust tips to direct the exhaust downward andsee if it makes any difference.

Are your floorboards full of holes?

Car is very solid, corrosion free, no holes anywhere. I like the thought of trying the exhaust extensions facing down. Worth a try thanks wagon man.

The tips may help and end the problem. Yah you knew a --but-- was coming. When you are at speed there will be a large low pressure area at the back bottom area of the trunk. If seals are bad may still enter the trunk. Mel

If it was my car I would start the car put on a pair of gloves and check around the exhaust manifolds.
Might want to crawl under the car and feel for holes in the pipes themselves. One persons opinion !
