Anyone know where I can get a ported exhaust manifold....exchange?

Neuspeed I think, or was that intake? Pretty sure it was exhaust.

Todd at AWE *may* have spare manifolds sitting around the he can offer on an exchange basis. Another thing to be aware of is that the Audi cast iron manifolds dont respond well long-term to extrude honing due to erosionary wear of surface smoothing offered by extrude honing. After a year it's scored/rough again and its inner surfaces look like the lunar surface or a sponge at 20x magnification... all pitted out. Prolly doesn't hurt anything but little evidence of EH remains.

Inatake side adapts very well tho and seems to last forever.

I have a manifold sitting in my garage. Email me.

Thanks for the advice. I think that's why Neuspeed puts a ceramic coating on the manifold after the extrude honing is done. Also, the EH process removes material and opens up the ports for more airflow. Although the surface may become rough, it still should allow increased flow.

Please advise if anyone has more input.
