Two pics I took last night comparing Calspeed and Kooks.

As you can see there are MAJOR diffrences between the 2 collectors.
For those of you that don't know, the collector is where 70% of the power is made from a Long tube header. Other areas include Equal or Tuned length primary's, Stepped primary's, Collector length and collector scavenging spikes.

Specs on each set are,

Calspeed, 1 3.4" primary with 3" collector.
Kooks, 2" Primaray with 3.5" collector With collector spikes.

This is a collector scavenging spike.

How they look inside a collector,

Reason I am showing you guys this, is that if you have the capabilities or know a friend who does. You can cut off the bad collectors and weld on a spike and a MUCH better collector. Effectively turning some Cheap headers in to a highend set with all the bells n whistles.

Depending on what your HP goals are I would stick with the Calspeed and save some money. You would probably have to be 500HP+ to see any gains with the Kooks over any other headers with 1 3/4" primaries and 3" collectors. Just my .02 cents
