Someone school me on header size.

Dougs will be about 5hp behind a set of tti's on a 360 with 440hp and that is really about it.

The hookers are worse than the Dougs and don't fit for crap.

We saw ZERO increase over tti going to a straight 1.75 or 1.875 header. The bigger headers were softer down low and no benefit to the top of the range at ~6K.
