**Some M54 engines have an extra 8 unused threaded holes hidden under the stock manifold flanges. In that case, you could install 8 additional exhaust studs/nuts and then be able to utilize all 24 header mounting holes. It is also possible that your car will not have these extra holes drilled and tapped. Must remove original manifolds and check cylinder head for hole count.
