I am trying something new and I combined all the detailed shots of the 2021 BMW M3 and M4 (aka F80 M3 and F82 M4) M Performance Parts BMW has released. The most notable that many will want is that supercar like center exit exhaust. For all the parts check out the video above!

  • Danny, maybe you can better answer this question. I like this center exit exhaust but wouldn't a pure diffuser be better for cleaning up the airflow OR is this central exit exhaust a better remedy by pushing the exhaust gases straight out the back to clean up air flow?

    Have been curious about that since first seeing this option.

    • a diffuser would, if it was a full flat bottom design. about the exhaust, obviously it is hot air. I am not a scientist, but there is something with hot air, areas of low pressure etc. that having the exhaust center can be better to suck the back...
