Exhaust studs are a common replacement item - they are easily ruined by rust, oil, and other chemicals. They are easily cross-threaded into the cylinder head or from the copper nut. And the nut and stud often come out together with the nut seized to the threads. It's always a good idea to have some spare exhaust studs on hand for an emergency or plan to replace a complete set any time a manifold is off.

This is a Genuine BMW M7 exhaust stud with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
