The F Series (1,2,3,4 Series) N55 cars all share the same downpipe. When first introduced, the downpipes had a 3.5″ v-band flange intlet on the turbocharger side. On 07/13, BMW decided to change the downpipe. This new downpipe featured a 4″ v-band flange inlet instead. Thus, the previous downpipes are not compatible with the new ones. See Below:
335i (U.S. Spec) – Up to 07/13 have the old downpipe (BM-EXH007)
After 07/13 have the new downpipe (BM-EXH012)
435i (U.S. Spec) – All 435i have the new downpipe (BM-EXH012)
M235i (U.S. Spec) – All M235i have the new downpipe (BM-EXH012)
M135i (European Spec) – Up to 07/13 have the old downpipe (BM-EXH007)
