That is an M5 badge, but it is an M car! Honest guvnor! My 540 is for sale as it happens. It's a manual one too if you know anyone...
Sorry, mis-read your original post and thought you said it was a 540
I'm jealous, I love E39 M5s long time

Yeah it's pretty sexy. Fast too especially after the decat! Though. Haven't yet found a comfy seat position, there's too many adjustments! Lol.
interesting
Can't really see the point, they'll flow pretty much as bad as a cast log manifold which is cheaper (or free as its standard) and hardly ever fails.
Of course I wouldnt want one if it flows like a standard. But Im presuming they can be made with larger bores.
They look nice, but why not just buy a steam pipe manifold?, it'll flow better and will never crack!
because mild steel steam pipe flakes as it oxidises under high temps and can still cracks anyway. any manifold that has a weld can fail.

If that don't do the job, then what you want is INCO which has cobalt in it.

It's going to cost. At least 3x more than stainless and maybe 4x. It should be cast, welding OK for N/A F1 but won't be for turbo. For low volume or one offs that means lost wax or lost foam.
this,
i have yet to see a correctly made manifold with c marked 321 stainless steel, coupled with a correctly supported turbocharger assembly and fit for purpose exhaust joints, would not crack under normal road/track day conditions.
the company i worked for used Inconel (amongst other W alloys) to manufacture exhausts for Ferrari and Maserati and commented on how well it formed and welded!
Just as you mentioned cost is usually the defining factor in this particular application!
