Its that curve that makes this so intriguing. It almost completely gets rid of the dead spot in our rpms that drive me nuts. Im very excited to get this. Hopefully the 15th , they arrive
. That rumble is a added bonus that almost makes it worth buying alone. the couple horse power total gain is nice, but the gain throughout the rpms is what makes this make a difference. I wouldnt be supprised if with the right na set up, and a tune, with these headers and e85 , will be seeing alot more 200 + fr-s and brzs out there. Hopefully jersey gets e85 sometime soon.
