Performance Cat-Back Exhaust System

This system is mounted behind the catalytic converter and features smooth mandrel bend construction to minimize restrictions, allowing the engine to perform more efficiently. It includes a free-flowing center pipe that splits into dual mufflers, each equipped with engraved STI tips for a distinctive look. This performance exhaust system is specifically designed to fit Subaru WRX models from 2002 through 2026. Earlier model fitment may vary, and it is recommended to confirm compatibility with the retailer for specific year ranges outside of the 2015-2019 range explicitly listed on some sites. The STI Performance Exhaust System is considered a special-order, non-refundable item. It is advised to contact the retailer directly with any accessory fitment questions to ensure proper installation and compatibility with your specific vehicle configuration.
