The Korsh catless twin scroll downpipe is a direct-fit upgrade for the 2008–2021 JDM Subaru Impreza STI. Engineered to complement the factory twin scroll turbo setup, it removes the restriction of a catalytic converter entirely – ideal for track, motorsport or off-road use where emissions compliance is not required.
Full 304 stainless steel construction resists corrosion and handles extreme heat cycles, while a precision wax cast twin scroll head flange seals to the turbine housing to eliminate leaks and maintain spool characteristics.
Why Korsh?
- Catless Design – Maximum exhaust flow and minimal back pressure.
- 304 Stainless Steel – Corrosion resistance and durability under extreme heat cycles.
- Wax Cast Twin Scroll Flange – Leak-free seal to the twin scroll turbine housing.
- Bolt-On Fitment – Direct replacement with no cutting, drilling or fabrication.
