1. A mixer arrangement for mixing an injection medium with exhaust gas of an internal combustion engine, comprising:
an exhaust gas guide section with a plurality of first threaded holes together forming a first threaded hole pattern and a plurality of second threaded holes forming a second threaded hole pattern;
an injector configured for being attachable to the exhaust gas guide section and having a plurality of mounting apertures forming a mounting hole pattern;
wherein each of the first threaded hole pattern and the second threaded hole pattern is complementary to the mounting hole pattern,
wherein the number of the first threaded holes, the number of the second threaded holes and the number of mounting holes are the same; and
wherein the first threaded holes and the second threaded holes are configured such that the mounting apertures are alignable with the first threaded holes without being aligned with the second threaded holes and the mounting apertures are alignable with the second threaded holes without being aligned with the first threaded holes.
