Also, any idea of how long the install time is? Would help me figure out how much it might cost to install it.

Edit: After doing some more research it seems that the gains are not worth the time/cost for the Stillen headers. Seems to be only 2-3 whp gain up top and actually lose some TQ.

Is that in peak numbers? Or throughout the powerband? Was it tuned for the headers or just bolten on/dyno'd?
