anyone know who produces these?

he told me NOT to go completely catless, as the f10 m5 needs both pre AND post-cat sensors for fuel/power management. this is not first hand knowledge so if any of you have knowledge to share on the subject id appreciate it.

they will be accompanied by an exhaust as well. thinking Eisenmann race or Meistershaft, but not completely decided yet.
The EAS website has a couple of options one of which includes a high flow cat.
