Unfortunately I appear to have hit something (I believe on the M11 just before Christmas) which bent the flange steady on the join between the manifold to the mid section. The force was enough to strip the nuts clean off of the bolts, though the rust probably helped here as there is no thread left (see below!). Annoyingly, the force of the impact was enough to also crack the exhaust manifold sections (both of them!), at a weld joint / bend close to the O2 sensors (circled below on the Real OEM drawing). It should be OK to weld it once off the car, though I thought it might be worth seeing if there are any good condition used ones out there first.
I'm based in South Essex but am happy to travel (obviously not in the Z4 sadly, it is SO LOUD
now!!) to pick up a new manifold section.
EDIT Sorry should have added it's a 2003 Z4 2.5i Auto
