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

yea, those were the only live pictures i could find, some other people have gotten headers with incomplete welds or small exhaust leaks at welds, etc, just little issues that shouldnt arrise on a set of 1500 dollar headers
the markup is insane for BMW’s and the people take it, i find it really funny that they are willing to accept that supercharger kits cost 14k and single turbo kits 16k
especially when some of the SC companies make kits for the regular 3 series and they cost 5k and the M3 kit costs 9k and the only diff is the m3 kit has a sheet metal intake manifold, but they pay it, so why wouldnt the companies that sell it continue to do so
