Expreme Ti Cat-Back Exhaust

The Tomei Expreme Ti cat-back exhaust serves as a specialized performance upgrade for 2002-2007 Subaru WRX and 2004-2007 Subaru WRX STi platforms. Constructed from high-grade, heat-treated titanium, the system prioritizes weight reduction and efficient exhaust scavenging. Its design incorporates a straight-through racing layout and a high-flow silencer to improve exhaust velocity and engine response. The system is engineered to provide an exhilarating race tone while significantly decreasing total vehicle weight by over 65% compared to stock components. The kit arrives as a complete three-section assembly, which includes a silencer tail pipe, main pipe A, main pipe B, and all necessary gaskets, clamps, and hardware required for a direct-fit installation. This exhaust system is explicitly designated for competitive race use only. Compatibility is limited to the specific model years and trims listed, ensuring a precise fitment for the GDB chassis configuration. By optimizing exhaust path geometry, the system aims to achieve increased horsepower and torque through enhanced flow characteristics. The use of premium titanium materials ensures durability under demanding track conditions while maintaining the lightweight profile required for competitive motorsports.
