A few Reasons, the additional cost does not justify the gains.
They are a Tighter fit.
They are Heavier
Most manufacturers offer a 1 7/8 headers so they are easier to get.
The biggest gains from headers are in the middle of the curve where you drive most and you can't tell the difference between 1 7/8 and 2 inch, on the dyno graph or in the car.
Unless your Racing you won't miss the 5 HP at 6300 RPM, your not there enough to use it on the street.
Hope this Helps.

I'm with him. If you are making over 1,000 HP or something crazy like that then I could maybe see the need for 2" but for the Majority of us, 1 7/8" is more than enough.
All the best,
