Hey guys I've a 1992 525i and my muffler is about to die. I know that my bimmer have dual pipes and I would like to know if I could connect an Y pipe to connect a single inlet muffler.

Yeah, you could. Just make sure the single inlet is large enough to not create a bottleneck in the system, calculate the area.
