exhaust manifold difference, 330 vs 328??
How different can they really be if both blocks are N52? Has anyone with a 330 used an exhaust manifold with cats from a 328 or vice versa?
http://bmwfans.info/parts-catalog/18407545308 This shows that the 330i exhaust is the same as the 325i, which means it was only in production for 1 model year... Thanks! |

The later part number supersedes the earlier one. Same part; bmw just updated the part number
Edit: Interesting aside, the latest revision # includes the F25 X3 w/ the N52 engine |

If you are looking for a factory exhaust manifold upgrade, some euro countries have different ones.
Depending on emission laws there there are some(instead of the log style manifold) that have shorty heaters with the same cats, and some with shorty headers and smaller cats |

I can confirm, as when I was looking to buy those from the second pic it took me probably 1 year to find them with extensive search. Even in Europe not all 330i cars are with them, for example UK cars are with the ones from the first pic and as far as I know all 325i and 323i cars regardless of the region are with the one from the first pic, so they are not something you see regularly.
