Could be a small leak in the exhaust that closes up as things heat up. Try to locate it quickly right after starting a cold engine.

Ask someone to plug the tailpipe with a rag while you look under the car for the leak.There will be a definite change in tone of the exhaust system.Do this on a cold engine.
