HKS Sport Exhaust Systems are designed to reduce backpressure and increase exhaust flow for greater peak power and a broader torque band. Each Sport Exhaust application utilizes a specific muffler design and shape along with the appropriate piping diameter to maintain low-end torque while maximizing high-end horsepower. This newest release for the 2002-2007 Subaru WRX/STI gives Subbie owners the option of unbridled performance and an OEM look without the noise of other exhausts.
