KORSH Titanium Cat Back Exhaust

KORSH Full Titanium Catback Exhaust System – Subaru WRX (GV/VA) / STI (GV/VA)

The KORSH Full Titanium Catback Exhaust System is the ultimate performance upgrade for the Subaru WRX (2011–2021) and WRX STI (2011–2021). Crafted entirely from high-grade titanium, this system is engineered for drivers who demand the absolute maximum in weight reduction, thermal efficiency, and exotic exhaust acoustics. By replacing the heavy factory steel assembly with ultra-lightweight titanium, you significantly enhance the power-to-weight ratio and handling precision of your Subaru.

The 76mm (3.0") mandrel-bent piping provides an unrestricted path for exhaust gases, allowing both the EJ and FA engines to breathe more freely for improved turbo spool and peak power. Titanium’s unique material properties offer superior heat dissipation and a crisp, resonant boxer note that is distinctively sharper than traditional stainless steel systems.

Key Features

• Ultimate Weight Reduction: Full titanium construction offers massive weight savings over the OEM exhaust, directly improving vehicle agility and braking performance.
• Full 76mm (3.0") Flow: High-flow mandrel-bent design minimises backpressure, delivering substantial gains in power, torque, and throttle response.
• Signature Titanium Acoustics: Produces an aggressive, metallic exhaust note with a refined 92dB sound level, perfectly tuned for the GV and VA chassis.
• Show-Quality Aesthetics: Finished with premium burnt-blue titanium tips that provide a high-end, motorsport-inspired look.
• Superior Thermal Properties: Titanium dissipates heat faster than steel and is virtually immune to corrosion, ensuring the system survives the harshest driving conditions.
• Direct Bolt-On Fitment: Precision-engineered to utilise factory mounting points for a secure and straightforward installation on sedan models.
