Korsh Twin Scroll Downpipe – JDM Subaru STI 2008–2021 – Catless

Application: 2008–2021 JDM Subaru Impreza STI (twin scroll)
Part Type: Catless twin scroll downpipe
Part Number: KOR-DPTS-08

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.

• 1 x Korsh catless twin scroll downpipe
