KORSH Catted Downpipe – Subaru WRX / STI / Liberty GT / Forester XT
The KORSH Premium Catted Downpipe is engineered for high-performance Subaru models, including the WRX STI (2008–2021) and WRX (2008–2014). This exhaust upgrade features a full 76mm (3.0") bore, specifically designed to enhance exhaust flow and turbo response while maintaining emissions compliance through an integrated high-flow catalytic converter.
Constructed with a high-quality cast bellmouth head, this downpipe provides a smoother transition for exhaust gases exiting the turbocharger compared to standard welded versions. Available in both Manual and Automatic configurations, it is the perfect solution for owners wanting increased power and a deeper boxer note without the environmental drawbacks of a catless system.
Key Features
- Full 76mm (3.0") Bore: Provides a significant increase in diameter over the restrictive factory piping for improved top-end power.
- Cast Bellmouth Head: Features a high-velocity internal design to reduce backpressure and improve turbo spool-up.
- High-Flow 200 Cell Cat: Metallic catalytic converter provides excellent flow characteristics while ensuring the vehicle remains emissions compliant.
- Mandrel-Bent Tubing: Precision 76mm mandrel bends ensure consistent exhaust velocity throughout the length of the pipe.
- Transmission Options: Available in specific configurations to suit both Manual and Automatic models.
- Global Fitment: Engineered to be compatible with both Right-Hand Drive (RHD) and Left-Hand Drive (LHD) vehicles.
