Description

The HKS Sport cat-back exhaust is designed as a stock-replacement system for the 2002-2007 Subaru WRX and 2004-2007 WRX STI, perfect for daily drivers who want better looks, performance, and sound without anything too loud or obnoxious. Each Sport application uses a specific muffler design and shape with the appropriate piping diameter to reduce backpressure and increase exhaust flow for greater peak power and a broader torque band.
