N54 vs N55 PE Mufflers- are they the same?
Hey everyone! I'm being offered N55 Performance Mufflers for my N54 E90. I already bought an X pipe to replace my midpipe.
The big question is: are N54 PE mufflers and N55 Mufflers the same(sorry if this has been asked before)? Could someone please chime in? Thanks in advance! |

f they are a different part number, I would say theyre different internally. I have PE on my n54 with no secondary cats and it is quite a bit louder than before. It would make sense if the n55 PE muffler is quieter to compensate

There are tons of threads about this. Both n54 and n55 will bolt up. The exhaust tip might vary.

From listening to a lot of clips it seems like the N55's PE are louder. But, since not all of them are without 2nd cats do you think they have different mufflers for each setup? It's very interesting to know if someone has a N55 PE on a N54 and what the outcome sounds like. When you deleted your 2nd cats did your check engine light up?

Just in case if anyone is curious, the N55 mufflers do work just great!
