Nope. It did not work. The m3 headers hit the bell housing and the pipes are at the wrong angles. Maybe if I had a shop I would attempt this, but doing it in the street and only 2days with the car before having to use it for work doesnt work. Also the oval pipes on the stock manifold would need a lot of re working. But an idea would be to use s50 headers. Those have the right manifold mount for the m54b25. Just add cats if your trying to be legal.
