Keep cracking/breaking flex pipe

[Pete379]

Cracking on both sides like that would lead me to believe your not getting enough flex. On my Pete when it gets too much flex say from a bad mount bushing they only crack on one side. Maybe check and make sure the flex section is not too long and is being forced in there between the two clamps.. It's either too much or not enough flex causing that.... I may be wrong but that's one place you can start in your search to fix
