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 during a full-throttle pull.

Overall, we felt that this particular muffler was going to be a bit much for most folks seeking an upgraded exhaust system. Yes, it’s loud, which can be fun, but that fun lasted around 30 minutes before we were over the initial excitement. Our assumption is that most people would not want to live with this muffler setup on a daily basis. For a weekend vehicle, perhaps it would work, but how many people would keep their 15’ WRX in the garage as a “weekend driver”? Not many, would be my answer.

Check back with us for a second video featuring our selected muffler design. Our professional video team will be working on it to better capture the audio for your viewing pleasure.
