i don't know whether or not most machine shops have the equipment to do this but abrasive flow machining process can be used to hone in the insides of manifolds. I'm looking to get the inside of my stock cast manifold honed.

Does anyone know of any local places that can do this process?

Where I work at 8081 Centreville Rd manassas Va called C and C We have a flow bench 7033687878 ext21 were on 28

 

lol John, do you know how expensive extrude honing is?

 

not as expensive as an after market manifold that wont crack.

good ideas FTW.

 

lol 3-400 bucks is way too expensive for only an extrude honing to me
