N55 (no secondary cats) = BMW part # 18307599743
For the OEM bolts and gaskets part #, see these earlier posts of Dackel:

Call around for the N55 midpipes because some sellers over-charge. Normal price is
sub $400.
N55 (left) versus N54 midpipes (right):
If you also change downpipes, the ECU will throw codes at you (detecting the absence of primary cats) which you need to deal with (no such thing if you only change mids) + might result into undesirable results (too loud, too smelly, trouble with authorities and neighbors). See for example:
