The plate you have here for protection is really hampering the ability of the system to move when the engine flexes on the mount or the frame flexes during articulation, might wanna try and loosen it up a bit?
edit: The way yours cracked, I would bet that this section failed to let the system move and it was engine movement (torqueing) that actually caused the crack. The flex joint between the cat and header would solve this problem.
Acctually it has 3/4" of clearance on every side of it. The plate is only there for structure rigidity since I cut out a huge chunk of a primary cross member.
you need to un weld it at the end of the header befor the cat, i use a extended slip joint, plenty tight with minimal leak, but allows the engine flex and keeps the pipe from causing twisting force on the header
The header has a ball flange that I guess I could loosen a bit. I like the idea of the flex joint though.
Factory down tube had a clamp at the bellhousing to stabilize the header. Do you still have this? If not, try it.
Don't have it. How would it adapt to an aftermarket header.
