HKS GT Extension kit for the Mitsubishi Lancer EVO X

HKS introduces the new GT Extension kit for the Mitsubishi Lancer Evolution X
 
                                                  MotoIQ Staff Report
                                         
HKS USA, Inc., the premier manufacturer and supplier of premium automotive performance systems, is proud to introduce the key item in exhaust back pressure control, the GT Extension kit for the Mitsubishi Lancer Evolution X. With the R & D information gained from theJapanese HKS EVO X, CZ200S limited production tuner car, maximizing the performance from the stock turbine was the primary focus of the new GT Extension kit. Replacing the factory extension housing, the two-piece, stainless steel GT Extension kit also includes a front pipe that bolts up to the factory catalytic convertor. The clean stainless investment castings are pretty impressive to us!  No backpressure enhancing neckdowns will be found due to poor mitering and other shoddy bits of workmanship like you will find in those fake knock off ebay parts.  HKS makes the real deal.
 
HKS has been able to reduce the exhaust interference caused by single-port extension housings by using two separate ports for the turbine impeller and the wastegate actuator. The result is a smoother exhaust flow and a reduction in backpressure enabling consistent and improved turbocharger boost response throughout the RPM range.  We have found quite a bit of value in separating the wastegate discharge flow in internal wastegate turbos to be very beneficial in our own testing so HKS is spot on here, with some good engineering.
 
 Manufactured utilizing a lost-wax process ensures durability and reliability. The HKS GT Extension kit is available now through authorized HKS dealers and is designated for Off Road Use Only. For more information, visit www.hksusa.com.

When Investment casting, the wax mold is destroyed in the process, so how do they form the new molds for a part with geometry like this? Probably not CNC machined, and I don't think it would be RP'ed either, my best guess would be some sort of die casting process, but I can't see any flash I'd associate with the wax being formed in a die.

Looks like the old LIPP SS O2 housings for the DSM's and Evo VIII/IX turbo's!

The wax isn't the mold. The wax is used to make a form which is dipped in a ceramic slurry. Then the ceramic is fired and the wax liquefies and is removed. The cermanic form is used as mold for the metal. When the metal hardens the cermaic is chipped away leaving the metal part.

My bad on the nomenclature, I've only got a little experience with green sand casting. I'm still confused about how the wax shapes are made in the first place though. I can't figure out how the internal curves are made in wax.

The wax is an exact image of the desired part, so when you dip it in the slurry, it becomes a shell and copies the internal contours as well.

A lot of turbine and compressor wheels are made with the lost wax method of casting. It is good for parts with complicated geometry or thin wall sections with sort of low production volumes. The tooling is cheaper since you are only dealing with wax.

The disadvantage is the processing time is very slow.

I wish they made this for the FC3S!
