Korsh Twin Scroll Downpipe – Subaru STI 2001–2007 JDM (Catless)

Application: 2001–2007 JDM Subaru Impreza STI (factory twin scroll turbo)
Part Type: Catless twin scroll downpipe
Part Number: KOR-DPTS-01

The Korsh twin scroll downpipe is a direct-fit catless downpipe for the 2001–2007 JDM Subaru Impreza STI. Engineered to complement the factory twin scroll turbo setup, it removes the restriction of a catalytic converter entirely for track, motorsport or off-road use.

Full 304 stainless steel construction and a precision wax cast twin scroll head flange give a perfect seal to the turbine housing, eliminating leaks and maintaining spool characteristics.

Why Korsh?

• Catless Design – Maximum exhaust flow and minimal back pressure for track use.
• 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 – No cutting, drilling or fabrication required.
