    URD just finished test fitting the updated version of our Spec-U Equal Length Long Tube Headers for the 2012 and later Tacoma V6 with the air injection system.

    The test vehicle was is a 2012 Tacoma XRunner COMPLETELY STOCK other than the addition of our headers.

    Peak gain was 17 RWHP and 30 RWTQ

    Max Gain was 22 RWHP at 3500 RPM and 34 RWTQ at 3430 RPM.

    The most important thing to note is the Spec-U headers makes power throughtout the ENTIRE RPM range. NO LOSS IN LOW END TORQUE.

    The truck is beautiful and I hope the owner forgets to pick it up!!

    The headers have been cleared for production and we expect to start taking orders in about a week and shipping in five weeks.

    I would say the same or maybe more on the XRunner. The 09+ stock manifolds are much different and look as if they flow better than the earlier version.

    The only change in the Spec-U was the air injection ports.

    I am hoping in a couple of weeks on the current version. Had a problem getting the needed flanges made. That held things up a bit.

    I wish I would have waited for these now instead of purchasing my AFE Twisted Steel Headers.

    No, our flanges are mild steel. We tried 304 in the past and it proved to soft.
