Looking for a better way to mate your 3" downpipe to the stock cat-back exhaust? Sick of blowing out gaskets and smearing copper sealant all over your flanges? Mishimoto now offers a 100% stainless steel downpipe adapter flange specifically for mating to a stock exhaust system. If you have a 2002+ WRX or STi, this is the piece for you! Check it out.

Prototype Fabrication
After experimenting with some boxed designs in Part 1 of this write-up, it was time to turn our attention to a shrouded setup, similar to what we offer for the 2008-2014 models. We're hoping we could utilize the piping from our existing kit, which is well designed and has proven power gains. After placing the shroud into position, we found that it would certainly fit, but would require some modification. The fabrication work began! Check out a few shots taken during the process.
Once all fab work was completed, we had a functional shroud that we could use for testing purposes. We could also use this shroud to develop a 3D model for our production units. Take a look!
Introduction
Our team is finally working on some cool components for the new 2015 Subaru STI! As you know, the 2015 STI is essentially a hybrid of old and new Impreza components. It features the newer body style paired with the trusty EJ engine, instead of the new DIT motor featured in the WRX. We won't get into which is better or which we prefer, because we have nothing but praise for the updated chassis. Our team has spent a great deal of time with both vehicles, and we are impressed with how the STI drives, handles, brakes, and functions as a comfortable yet sporty sedan.
As you may already know, we developed an intake system for the 2015 WRX recently, and we had a ton of success producing some really nice power gains. We also offer an intake system for the 2008-2014 WRX/STI equipped with
Time to review our data so we can finally put a close on this project. The product development process for this front-mount intercooler has taken months and has also helped refine several of our processes. Before we move into the testing data, our first portion of this post will cover the physical benefits of our intercooler. By providing a more efficient heat exchanger, we can ensure that higher-powered vehicles are not being hindered by debilitating heat-soak and/or inefficiencies with the use of a top-mount intercooler setup.
Our first comparison point is internal flow area. This graph shows the volume of the actual air passages through the intercooler.

We are nearing the end of this build. As mentioned in the last post, we wanted to put our core to the test and provide some cooling efficiency data that our customers could use. We decided to modify our 2010 STi to add some heat and power to the CAC system for testing. Information regarding our vehicle is listed below.

As you can see, we have sensors installed on the piping, both the cold- and hot-side of the intercooler. We have pressure and temperature sensors hooked up
As promised, we have a couple cool images showing these kits fully installed on our test vehicles. Check them out below!
First, our full kit installed on our shop 2003 WRX Bugeye wagon!
This intercooler fills out the bumper completely and looks fantastic. Next up, a look at this kit fully installed on the Hawkeye.
And a couple shots of our finalized GR STi kit!
Now that we had all of our kits developed, the project is complete, right? Wrong! We haven't tested this intercooler out yet! Now, we have conducted a ton of CFD and core

Once the engine bay was evaluated, we began to fabricate piping. Our goal was to route these pipes in the cleanest possible fashion while keeping the route as short as possible. First, the upper portion of the pipes were mocked up and tacked together.
Special attention was given to clearances between the intercooler pipes and the engine/engine bay components to ensure nothing would be rubbing or vibrating during operation.
Check out a few shots of the finished pipes mocked into position.
Now is a great time to recognize the talents
As you may be aware, our team recently had a 2015 Launch Edition STI in our shop so we could evaluate the vehicle, determine which of our current products fit properly, and begin designing a few new additions that would be specific to the 2015 model. Check out the video below featuring our Subaru expert, Jason. He discusses the changes that have been made with the new model and what Mishimoto components we were able to fit onto the vehicle.
Stay tuned for additional information regarding our upcoming products for the 2015 STI!
Thanks for reading!
Now that we had our battery tie-down finalized, we could focus on the next component we wanted to tackle in the engine bay. Our next target would be the radiator stays, the small stamped steel pieces holding the radiator to the radiator support. We offer anodized aluminum radiator stays for a variety of vehicles including the previous generation WRX/STI, Honda Civic, and Ford Mustang.
For this particular project, we would be following a similar route. Our stays would be produced in aluminum and then anodized in a variety of colors to match an engine bay accent color. Before we get into the Mishimoto design, take a look at the stock components.
Following our standard product development procedure for smaller components, we designed our stays in Solidworks and printed them using our 3D
