Z4 E85 (M54B25) Has anyone changed, installed "Supersprint" exhaust manifolds, a Chinese copy? Can you tell me how they fit? Need some work on the flanges?

I can't speak from experience on the headers but from everything back super sprint was direct bolt on for me, so I'd "assume" SS headers should also be direct. Keep in mind some have had issues with bad fabrication from manufacturing, If you run into a problem contact them right away before adapting them as they might have manufactured it poorly if it's not a direct fit. Before fitment put old/new headers side by side, if they're way off don't try anything before contacting them as to why. I have racing dynamics headers which were direct bolt on no modification other than where the post O2 sits the heat shield there had to be trimmed a bit for clearance of the O2.
 
I choose from copies made in Russia or imported from China. There are two options in the photo.
