Extrude Hone. It's the company name. They cap off the end of a part and squeeze an abrasive goop through it to smooth out the interior. In our case it removes the casting roughness in manifolds and adds performance. Many of us old-timers have been using them for decades. It's far easier than trying to polish an entire part, especially something difficult to reach with porting tools like a headpipe or long manifold.Tim, i used to hear the term extrude hone way back in the day. Some peps on here might not know about that. Is there a company doing that?
I'll match your picture and raise you a video...A picture says a thousand words...

Here two pictures of where we drill and tap for water routing. Water goes into very bottom fitting, 80% water comes out in the new fitting in the back, last 20% water goes out the top.
Change the restrictor in top to add or reduce water flow.
More water out the top less the motor will rev and pull little better on bottom
Manifold but not the head pipe. Also open the manifold up to 46-48mmAre these still available? What is the pricing now? Will they work with a Coffman sizzler manifold and head pipe?
