Description
Upgrade your Subaru's exhaust system with the COBB Tuning Titanium Cat-Back Exhaust System, designed for compatible 2002–2007 Subaru WRX and 2004–2007 Subaru WRX STI models. Engineered for performance-focused Subaru enthusiasts, this exhaust system offers an aftermarket alternative to the factory exhaust, combining lightweight titanium construction with a performance-oriented exhaust design.
The cat-back configuration replaces the exhaust components downstream of the catalytic converter, providing an upgraded exhaust path while retaining the catalytic converter when installed in the intended configuration. Its titanium construction offers a lightweight alternative to conventional exhaust materials, making it an appealing option for enthusiasts seeking performance-focused hardware.
The COBB Titanium Cat-Back Exhaust System is designed to complement turbocharged Subaru builds, whether you're maintaining a street-driven WRX or developing a modified STI. Exhaust sound, flow characteristics, and performance results depend on the complete exhaust setup, engine configuration, and supporting modifications.
Manufactured by COBB Tuning, this exhaust system provides a combination of lightweight construction and motorsport-inspired engineering for compatible Subaru applications.
