Sorry, didn't know it was ok to advertise a business without being a registered vendor. There was already a guy who was doing ported/coated manifolds on his own like this and was forced to stop. He also put his own business URL in his signature, but was forced to remove it. If members don't report such things, how are mods to see it? I have been told to report such things...

Extrude honing just ups the CCs in the port by forcing a clay compound with cutting compounds in it by pushing it through the entire piece. not at all accurate.

Extrude honing is kind of a joke. The port cannot be controlled, only the overall volume of whatever is being worked is increased. There is no way to control or customize port shape. It's mainly good for pictures cause it looks cool.

The best thing to do is ask people via pm..I know you are not selling anything, not even making profit since the dam bits cost that price, but got some haters in here like they are a mod.

On the runners, it doesn't help to increase the openings unless the head is also ported to match. On the other side, you can port out a lot, though out to the size of the gasket. That's how all the BR stuff is done.

gasket matching a stock evo manifold has its benefits as for one you're removing hte minor head losses from the lip at the cylinder head and two if you smooth the flow from the head to the manifold in a gradual way you'll of course deduce that the manifold squishes the air before it ends up in the twin scroll, this is a very good thing for spool up.

Simply cutting away at all the material larger than the gasket would result in a large opening and no improved airflow. The manifold was ported to improve air flow direction and velocity into the turbo, no just create more volume overall. Thanks for your questions, it's nice some one knows what's going on, or wants to.
So then do you recommend gasket matching all exhaust systems as well?
See what you don't know about porting is where my machinist BEGINS. Air does not flow how you believe it to. And you don't understand airflow as well as you may think. If you'd like to know why things are done the way they are, you may call us Mon-Sat 9-6PM and ask him why he does that way.
A large reason a lot of "gasket matching" and opening ports to ungodly volumes I NOT done is because the TIME SPENT does not equal the PERFORMANCE GAINED. If you have more questions, please feel free not to highjack my thread without proper knowledge of airflow and simply call us to clear up the matter. This is not a discussion, it's a show of our work. He'll be here tomorrow by 8:30 AM Pacific Standard time.

not done yet, pics will be up as soon as it's complete. we're busy, lol. sorry for the inconvenience. We're down to do a customer o2 housing CHEAP if some one has one available! Let us know!
