    No. It only works with the whole Spec-U performance exhaust package.

    Should be ready to ship in a couple of weeks.

    You can place your order at any time. Back orders get shipped first in the order they come in.

    I just had this system installed yesterday on my 2014 4Runner. There are definite power gains going from the crushed stock y pipe. I will get a Dyno this week to confirm but my guess is 10-15rwtq all over the curve. The improvement in low end is significant... Which is not exactly what I expected, but certainly lives up to the theory/purpose of the equal length system. Gadget did his homework. This system is worth every penny.

    Yes sir. Waiting for your spec u headers for this application.

    Also can't wait to throw a URD supercharger on some day. Produce it and I will be the first in line to buy one.
