Subaru STi Baffled Oil Catch Can System

Mishimoto 2010 STI

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.

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.
