/\ agreed.
John I was thinking about it that with all 6 runners it may hold together better than a 4cyl manifold but you still have a lot of weight being supported and the exhaust will be even longer now. Even if you didn’t weld braces in, but used some spherical rod ends and threaded bar to help support weight it may save the time of having to fix cracks in the future. Plus it will give you some baller status as no one else in the bmw world does it.
If you want I’ll get you some pics of dsm support setups. Here’s my talon’s header after jethot.
3 3/8ths ss rods for support.
Oh and I sent you a pm for the heat sheilding.
