Gruppe N headers for S50 swap

[Beau B]

I have a sorce to get some Gruppe N headers for a really good price, I was wondering if anyone knew if they would work with the S50 swap? Thanks

What do they look like? Do they fit? CARB legal?

Thanks

Some one answer this so I can get one too, if it will work!!

are the headers made for an s50? if so, you can make them work if they don't already, although the only problem I can see is that they may contact the control arm bushing.. any exhaust shop should be able to remedy that

Yes they are S50 Gruppe N headers.

how hard it is to make the header work for a aftermarket 325 exhaust? Recomendations, I do not have much of a time frame to do this in.

If I use a good header (factory m52/s52 header) can I use like a 2.5 inch single pipe exuast that is not mandrel bent, because I have notcied that the system does not take any hard curves? I would like to use a free flowing system, but I do not have much money to blow on it right now.

I was reading this month's Roundel on the shitter yesterday... There was a feedback letter in there where a guy was asking about headers for his M3. The response was about manifolds on 3.0L and 3.2L M3 engines. It basically indicated that most guys wanted the 3.2L stock manifolds and headers were not necessary even with internal mods.
