996 Headers Help

  1. Had the 996 out this week couple of rides to work in the sun, started popping and banging on the overrun.

    and it’s cracked a the front cylinder header.

    now I’m pretty sure they are all the same regardless of exhaust size, 50mm goes over the top like mine and 45 inside… can someone please confirm?

  2. The 45mm pipe certainly goes inside the header but I'm not sure that a true 50mm header would have the pipe on the outside? I may be wrong but that doesn't looks right to me.

    As for the crack, looks an easy repair rather than replace.
     
  3. That looks like a 45mm header with a 50 mm downpipe stuck over the outside.
