Need to replace gaskets on the exhaust system - Item #4 shown here:
https://www.getbmwparts.com/v-2011-b...ust-components

Does anyone know the p/n or specs of the bolts/nuts that connect the exhaust manifold (Item #1 above) to the center muffler (below)? The existing bolts are going to have to be torched off, or heavily torqhes to break all the rust, so they are not likely going to be reuseable.

I'd like to get all the bolts/nuts ahead of taking the exhaust system apart to fit new gaskets in place.

By the way the ones from factory are studs, not bolts. And yes, they will most likely will have to be heated and hammered out because they won't have usable threads lefts on them from rust. There is no replacement stud but bolts.
