Just found this site. Wow. Great info. I have had my 72 914 for 30 yrs. Restored it 10 yrs ago. Still all original--fuel injected. Since then, it has been driven very little (unfortunately). In the last year, I have started getting a popping or backfire on decceleration. It is getting worse and worse. The car drives great and strong other than this annoying habbit. I heard about the exhuast leak possibility and put my had under the car while it was running. I can feel airflow under each heat-exchanger to head connection! Is this normal? I don't understand how ALL could be leaking. I used the copper rings when I connected them 10 yrs ago. Could they be going bad?? I need an expert!!

backfire on decel is "a" sign of exhaust leaks. If the car hasn't been fired in a year. I would do the old valve adjustment, check dwell and timing. Also, Check the exhaust bolts for tightness, but be easy, they can snap off when old. Try loosening them a little first. If they loosen easily, then try to tighten, but just a little past snug.
