yes they remind me of Euro N53 Stock Exhaust manifolds, Euro 5 compliant. Parts 18407568613, 18407568614.
I wonder if these N53 parts would work too, and if so, which would flow better. Which , in turn look like 2006 130i/330i Euro N52 exhaust manifolds,Euro 4 compliant: 130i: http://www.dparts.com/onderdeel/2890...-87N-Hatchback http://www.dparts.com/onderdeel/2890...-87N-Hatchback 330i: http://www.dparts.com/onderdeel/2879...erie-E90-Sedan http://www.dparts.com/onderdeel/2879...erie-E90-Sedan The plot thickens...

This is definitely cool stuff. I didn't get to go through your posts well the first time. Thanks for putting in the research.
In the case of the e46 headers, the fact that they are lighter is not fully explained. Is it because they used thinner piping? or is it the weight of the aftermarket cats, maybe both? The euro 330i headers are a cool design. I wonder if there are gains to be had by them. I would love to get my hands on a set. The flange at the ports looks exactly like the north american manifolds. So now we have the following and correct me if I am wrong: North American Headers for N52
Euro Headers

For z4, does SuperSprint claim their product works? North American 323i & 328i & 128i Are the same - NA version perhaps. Except the other user claiming later 328i got n53/euro style n52 manifolds. Euro 130i & 330i - Completely different collector = Perhaps same shape and all as the euro n53 EDIT: NOT likely to be the same shape and all as the euro n53. I looked at my own links again... euro 330i n52 has massive cats. Even for the 125i in europe, Euro 5 compliant

Yeah....this thread shows us that there is actually a lot of choice. I think the main categories are North American Collector, Euro Collector, and Magnaflow. I would like to see which operates best as a catless header.
I just checked the euro x5 3.0si. It has the same 3 pipe collector as the euro 130i. The plot thickens. |

Has anyone since been down this road? I might be willing to guinea pig the N53 euro headers. Got a friend that does work like this on the side.

I think you should check prices of Supersprint, email them directly. They surprised me with their quote. Seemed abit better than what you find from resellers

check my threads I have made. They are custom built from scratch stainless steel manifolds proven to have 12whp 15wtq and no sound increase.
does not come with any 02 sim. you can buy the bms downpipe fix for when you need to pass emissions. I believe it is recommended not to use the sim long term because it messes with lambda adaptations. |

All the places I've been to only check OBD "readiness" values and for any CEL involving emissions systems, no sniff test at all.
