KORSH Titanium Turbo Back Exhaust Subaru WRX (GV) / Subaru STI (GV/VA)

KORSH Titanium Turbo Back Exhaust – Subaru WRX (GV) / STI (GV/VA)

The KORSH Titanium Turbo Back Exhaust System is the ultimate hybrid performance package for the Subaru WRX (2011–2014) and WRX STI (2011–2021) Sedan. This elite system combines a heavy-duty stainless steel downpipe (KOR-EXHDP-08) with a featherweight full titanium catback (KOR-CB-15STI-TI) to provide the perfect balance of durability at the turbocharger and massive weight savings across the chassis.

By utilising a 76mm (3.0") mandrel-bent design from the turbo exit to the tips, this system drastically reduces backpressure and heat retention. The titanium catback section offers unique resonant acoustics that amplify the signature boxer rumble with a crisp, metallic edge, while significantly improving the vehicle's power-to-weight ratio and handling agility.

Key Features

• Hybrid Construction: Features a durable 304 Stainless Steel downpipe for heat resistance at the turbo, paired with a full titanium catback for maximum weight reduction.
• Full 76mm (3.0") Bore: Unrestricted mandrel-bent piping ensures maximum exhaust gas velocity, resulting in faster turbo spool and increased peak power.
• Exotic Titanium Acoustics: Delivers an aggressive, motorsport-inspired exhaust note that is distinctively sharper and more resonant than traditional steel systems.
• Signature Titanium Tips: Quad burnt-blue titanium tips provide a premium, show-quality finish to the GV and VA sedan rear profile.
• Transmission Specific Fitment: Available in dedicated configurations for both Manual and Automatic transmissions to ensure perfect clearance of the subframe and gearbox housing.
• Superior Heat Dissipation: The titanium section sheds heat faster than steel, reducing under-body temperatures during spirited driving or track sessions.
