[quote=“newman,post:36,topic:25593"”]

that didn’t crack on a weld. the fabrication is not the issue, judging by where it cracked (right near the bolting flange) it could have been one of a few things:

1. poorly supported exhaust downstream
2. bad material
3. bad motor mounts, too much torque for motor mounts
4. insufficient flex in the system after the header. I see nothing wrong with that header.

I think it was a welding issue. Maybe Hydrogen Embrittlement or no post weld stress relief. I think it was the latter or a combination of the 2. I have see this before and the cracks happen just outside of the weld boundary because that is where the material is thinnest.

edit: the thing was definitely stressed too
