I was hoping to get some insight into what seems like a somewhat common exhaust popping problem. I read all the threads I could find but they all seem to relate to closing the throttle on final, and that being the cause. The problem I am speaking about occurs on downwind when the CS prop and mixture are pushed full forward, while still under some lower power setting (maybe 1500rpms??). The the exhaust will pop/rumble repeatedly for a good 10 seconds or so before it quiets down. I didn't notice any power issues but the plane was in a slowing configuration at the time.
The engine is an O-375 with a Hatzell prop and dual mags. The idle speed is around 800-850 rpm. I don't know the exhaust.
Thanks! Andy
