Does anyone know if the 1M Secondary cats & resonator section of the 1M exhaust fits on the N54 135i? Thanks.

Yes. The secondary cats are located on the midpipe which is totally plug and play.

Thanks for the info! I ran over a rock on the highway and damaged one of the secondary cats. Is it worth just deleting the cats? I'm running the PE exhaust (with Y pipe, resonator delete) and will this dramatically increase the sound of the exhaust? The current sound/drone is bearable but I don't want it to increase significantly if I delete the secondary cats.

Louder for sure, but you won't regret it
