Support for F22b and F23a tuners! We are now offering a bottom mount turbo for T3 and T4 which has B.E.A.U.T.Y and Function all wrapped into one glorious offering towards a community which tends to be highly neglected for handcrafted aftermarket parts. Manifold runners are 304 stainless steel which are backpurged with argon to insure a quality weld inside and out. Our newest release of this manifold comes standard with a CNC machined collector.
