Dude that sounds awesome! When will you be getting a dyno? Recall that RelentlessRY said he saw a loss of torque in the mid-range with these headers, but we suspect that it's because he had the stock cats & cat-back, and that this issue goes away when the headers are combined with HFCs and a good cat-back. Now all we need is a dyno to confirm once and for all (which is why I'm so eager). Still, thanks for the video, as it at least puts to rest the 'high-pitched sound' concern. +rep.
