Our 10mm thick M104 exhaust flange set is designed for building your own turbo manifold, the ports are large enough to allow a “slip inside” fit of the primary tubes so that they can be welded from the inside (& or outside) if you choose. If you want to build a tuned length n/a header please check out our 8mm flange sets.
