KORSH Turbo Back Exhaust

KORSH Turbo Back Exhaust – Subaru WRX (GH/GR) / STI (GR)

The KORSH Premium Turbo Back Exhaust System is the ultimate all-in-one performance solution for the Subaru WRX and STI Hatchback (2008–2014). This comprehensive package includes the high-flow KOR-EXHDP-08 downpipe and a matching 76mm (3.0") catback system, engineered to provide an unrestricted path for exhaust gases from the turbocharger exit all the way to the tips.

By replacing the entire factory assembly, this system significantly reduces backpressure, allowing for faster turbo spool-up and substantial gains in power and torque. Available in specific configurations for both Manual and Automatic transmissions, it features signature Titanium exhaust tips for a high-end, motorsport-inspired finish that perfectly suits the wide-body GR chassis.

Key Features

• Complete Turbo Back System: Includes both the high-flow cast bellmouth downpipe (KOR-EXHDP-08) and the 3-inch catback for maximum performance efficiency.
• Full 76mm (3.0") Flow: Mandrel-bent stainless steel piping maintains a consistent diameter, eliminating the restrictive bottlenecks found in the factory exhaust.
• Premium Titanium Tips: Quad burnt-finish titanium tips provide a distinctive, show-quality aesthetic.
• Enhanced Power & Response: Designed to optimise exhaust gas velocity, resulting in improved throttle response and higher peak power across the rev range.
• Transmission Specific Options: Available in tailored configurations to suit both Manual and Automatic models for a perfect, vibration-free installation.
• Durable 304 Stainless Construction: High-grade materials ensure long-term resistance to corrosion and the extreme heat of a turbocharged boxer engine.
