BMW PE - versions / differences?
As I understand there are several Performance Exhaust versions in existence: 135i vs 128i variety being most obvious, also there supposedly exists an Euro version that I believe retains the flapper valve...
But how about the two specific 135i part numbers - 18100443575 (discontinued) vs. 18102208806 (current) shown in BMW NA parts catalog? Does anyone know if there are there any (internal) differences between the two? Diagrams look identical... but different part numbers suggest updates / revisions... or?
