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.

After driving with this setup in a variety of conditions, we had a few first impressions.

Highway drone is more than we would prefer.
Exhaust is too loud under normal driving conditions.
Turbo-spool noise is greatly amplified and sounds fantastic

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.

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

Once our design was completely tacked up and fitment was verified, we began the complete welding of our cat-back. We back-purged the piping to prevent "sugaring" of the internal portions of the weld. Yes, it is just a prototype unit, but we are planning to use this unit for sound testing to determine our muffler choice.

Subaru WRX/STi Cat-Back Exhaust

An aftermarket exhaust is an easy way to distinguish your car from the slew of vehicles roaming the streets. Not only does it enhance aesthetics, but the amplified noise is also a dead giveaway that you are an automotive enthusiast. For many of us, an exhaust is a simple initial upgrade that will enhance the driving experience and provide greater enjoyment. With a variety of options popping up, it can be difficult to select a setup that will provide the noise level and tone that you want from your Subaru.

We are no stranger to exhaust components. Many of you kept up with the progress of our build for the FA20 downpipe we developed and released a few months ago. Thanks to a skilled engineering team, high-quality materials, attention to detail, and impressive craftsmanship, we were able to deliver exactly the product that our customers needed.
