I agree with Patrick, those catted maxspeed headers look like not much thought went into designing them.
No need to go custom, come on guys do I have to spoon feed you everything
I have stated, you can't use 986 headers... what comes after 986... that's right headers designed for the 987, in particular the 3.4 in the Boxster or Cayman S. They have the right size ports and the primaries and collectors are pretty much the right sizes. The modifications needed to get them to work are minimal to none depending on the muffler and header choice.
Here is the Fabspeed on my car now, I also have a set of B&B. I am probably selling the B&B set if anyone is interested.
