KORSH Catted & Resonated J-Pipe – Subaru WRX / Levorg / Forester XT
The KORSH Premium Catted & Resonated J-Pipe is the essential performance upgrade for the Subaru WRX (2015–2021), Levorg (2013–2018), and Forester XT (2013–2018). Designed to replace the highly restrictive factory front exhaust section, this J-Pipe significantly reduces backpressure on the FA20DIT turbocharger, resulting in faster spool-up and increased mid-range torque.
This high-flow J-pipe features a premium 200-cell metallic catalytic converter to ensure emissions compliance while providing far superior flow over the OEM unit. Additionally, the integrated resonator is specifically tuned to eliminate unwanted cabin drone and "rasp," providing a refined yet aggressive exhaust note. Available in dedicated configurations for both Manual and CVT Automatic transmissions to ensure perfect fitment and subframe clearance.
Key Features
- 200-Cell High-Flow Cat: Optimises exhaust gas velocity while maintaining emissions compliance and reducing exhaust odour.
- Integrated Resonator: Engineered to refine the acoustics of the FA20 engine, delivering a deep tone while preventing highway drone.
- Enhanced Turbo Response: Drastically reduces backpressure at the turbocharger exit, allowing for improved throttle response and higher peak power.
- Transmission Specific Design: Available in tailored configurations to clear the larger CVT housing or Manual gearbox linkages.
- Premium Construction: Manufactured from high-grade stainless steel with precision mandrel bends for consistent diameter and long-term durability.
- Direct Bolt-On Fitment: Engineered to align perfectly with factory mounting points and turbocharger outlets.
