For a 986 "S" that is around the most efficent engine RPM & if you are installing headers you want the pipe size to be ideal for the intended rpm range. If you normally drive on public streets RPM range is 1,000-6000 so the best overall compromise is headers that give best exhaust velocity @ 3.000 rpm.
