The first was after about 120 hours, while the plane was still turbocharged. The turbo exhaust pipe broke off where there was a sharp bend. Probably too sharp, and probably not as related to vibration as it was to heat. The second break occurred about 2 months ago with my non-turbo installation. I have 4 separate pipes coming from each cylinder - they are not tied together. The #1 & #3 cylinders kept trying to break the hangar bracket (near the firewall, flexible material coming down from the engine mount). After breaking the hangar, the exhaust pipe for the #3 cylinder broke off at the exhaust flange. It was dangling from the EGT prope wire when I did my QUICK turnaround to land. I had been airborne about 5 minutes when it happened. That gets your attention. I now have a revised mount, but there is a still a flexible support coming from the engine mount to the pipe (each pipe is about 36" long - too long not to have some support). Matt
