PERFORMANCE MUFFLER (Low back pressure) WRX STI(VA)

This high-performance muffler boasts low back pressure, an approximately 16% lower airflow resistance, and a weight reduction of approximately 1.9 kg compared to the standard models. While complying with the safety standards and Type 1 after-market muffler performance tests, this muffler increases acceleration performance by approximately 2%, and makes the engine more responsive to the operation of the accelerator. This gives the driver of the performance-oriented SUBARU WRX model a sense of integration with the vehicle. In addition, the exhaust sound is tuned specifically to a sporty feel and high-quality sound that fits the character of SUBARU WRX.
