Anyone have a set of stock manifolds from a5.0 Coyote V-8 they would like to sell please PM me. Gonna send them out and have them extrude honed and then ceramic coated and then do a back to back dyno on a completely stock truck verses just the change to the manifolds.

Okay let me know. I was just about to give up. I am looking into getting them extruded honed to run them back to back on the dyno.

Sorry for the late reply I am still learning how to navigate this forum. No I don't need a set there is no gain to extrude honing the stock manifolds.

What caused you to change your theory? Did you have a chance to test what you wanted?

From what information I have gathered the manifolds are more efficient on the 2015 and newer manifolds and the cost to due the extruded hiring was going to be over 500.00 with shipping which puts it out of the cost to performance gains equation.
