The official Subaru performance accessories for the 2023 Subaru WRX were introduced by Associate Editor Byron Hurd, with one of the most anticipated upgrades being the STI muffler. Initially, the muffler was found to be extremely boomy, especially during the high-rpm cold start routine. This resulted in a loud and resonant humming throughout the car, making the overall driving experience less enjoyable. However, after several hundred miles, the muffler seemed to “break in” and the overall volume decreased, although some boominess still persisted at certain points in the rev band. Despite these drawbacks, the muffler had some positive aspects as well.
One positive aspect of the muffler was its clean and deep exhaust tone, with a boxer engine-like lumpiness during warm idle. Additionally, the extra volume provided a more engaging driving experience, particularly when rev-matching or driving the car hard. Surprisingly, the muffler was relatively quiet on the highway and drone-free at cruising speeds, making it more enjoyable for long road trips. Furthermore, the exhaust sound from the outside of the car was notably quieter compared to the noise experienced inside the cabin. The trapezoidal tips with STI logos also added a sharp and unique aesthetic to the overall look of the vehicle.
In conclusion, the STI muffler for the 2023 Subaru WRX is a slightly mixed bag. While it can be noisy inside the cabin at times, it still manages to be livable in certain respects. Subaru does not claim any horsepower gains with this upgrade, as it mainly consists of a resonator and tips without any revised engine tuning. Priced at $1,139.95, the muffler may not be worth the investment for everyone. Prospective buyers are advised to consider the pros and cons of the muffler based on their own priorities, listen to the video sample provided, and make an informed decision about whether to purchase this accessory for their WRX.
