I have the standard Vetterman exhaust with the hangar system he provided back in ~1999-2000. The system has two downrods that hang from the engine mount using adel clamps and a crossbar that goes between the two pipes. There are small pieces of aluminum angle that provide a locating point for the vertical and horizontal attach points. Both the horizontal and vertical hangars/spacers use welding hose for shock absorption.
Anyway, the issue is that every 5-10 hours, the exhaust pipes rise up and contact the firewall flange. I don't know if the cause is exhaust pulses, the slipstream, or whatever, but I'm tired of having to reach under the belly of the airplane and push/pull on the exhaust pipes to re-center them vertically in the air outlet.
I've tried adjusting the geometry of the exhaust hangars, but the problem always comes back.
Has anyone else experienced this? Suggestions? Solutions? Is there a revised exhaust hangar system that has proved trouble free? FYI, I seem to break something in the exhaust hangar system every couple hundred hours, and wouldn't mind installing a hangar system that's a bit more robust.
