It's not insane faster spool but it's faster spool nontheless. Instead of a smooth pull back now the car literally snaps and plants your head back.

Also note that simply slapping headers on won't help much....I actually lost power because the AFR went from 11.0:1 to 10.2:1 in the upper rpms. But tuning for the headers made all the difference.
