Crash Beam Fabrication

After an unsuccessful test fit of our existing bumper beam on the 15', we started from scratch to create a beam specific for the 15' chassis. First we hacked off the end tanks of our cooler so we were left with a bare core. This would provide some freedom to design our crash beam and later work on the end tank direction. Next we cut out some new mounting plates and fit them into position.

After developing a highly successful, direct-fit catch can setup for the 2015 WRX we turned our attention to the previous generation. Our next target would be the 2008-2014 WRX and STI. At this point, Mishimoto still owned a 2010 STI, and this project would be our last for our shop vehicle.

Subaru WRX/STi Cat-Back Exhaust

As promised, we hit the road to begin testing our prototype designs. Our first round of testing was purely to evaluate the tone and sound level of the exhaust.

What are we looking for?

• Rich tone
• Little to no rasp
• Minimal highway drone
• Noise amplification from one-half to full throttle

As you know, the FA20 utilizes an equal-length header, which means that the traditional Subaru rumble is likely to be lost. Either way, we would be looking for a nice tone that would be acceptable for daily use.

Our first road test utilized our smaller, round style muffler.

15' WRX testing

Already outgrowing the efficiency of your 15' WRX top-mount intercooler setup? Planning for some big power in the near future? Sounds like your Subie needs an efficient front-mount intercooler (FMIC)! Luckily, our team has been working to develop this product for months. Check out the process below!

Cooling systems on older BMW models have been recognized as a frequent failure point requiring regular replacement to avoid catastrophic failure. This includes anything made of plastic within the system. So far we have a few remedies - an aluminum radiator and a silicone coolant hose kit. The mechanical fan is next on our list to be addressed.

The stock fan setup is certainly efficient in keeping your straight six cool. That said, a fan failure can get quite ugly with

Size Comparison

Before installing our prototype cooler on one of our 2015 WRXs, we decided to take a few shots showing the huge size difference of our cooler compared to the stock unit.

Prototype Fabrication

With the front section of our exhaust complete, we needed to address the Y-section as well as the pipes routing to the mufflers. We decided to go with 2 1/4" piping following the Y-section, which matches the diameter of the STi system.

Check out a couple shots from the fabrication process.

Fabricated muffler section

We bent a few more hangers for attaching the mufflers to the appropriate stock locations.
