Description

RADICAL EXHAUST RESTRICTION ELIMINATION – DRAMATICALLY ENHANCED FLOW FOR THE 4G63.

The Unlimited Turbine Outlet for the Lancer Evolution IV, V, VI, VII, VIII, and IX represents a fundamental improvement in exhaust system architecture.

By addressing the severe restriction at the turbine exit—the most critical point in the exhaust system—this component delivers substantially improved exhaust flow, enhanced engine protection, and measurable performance gains.

Product Highlights

⚙️ RADICAL FLOW IMPROVEMENT – 70mm INTERNAL DIAMETER
Engineered to eliminate the critical bottleneck at the turbine outlet:

• Factory CT Series Outlet Restriction: Severely limited to 55mm diameter

• Unlimited Turbine Outlet: Full 70mm internal diameter secured

• Result: Dramatic improvement in exhaust flow efficiency at the most critical point in the system

🏎️ SIGNIFICANT PERFORMANCE GAIN
By drastically increasing flow capacity immediately after the turbine, this outlet enables:

• Reduced exhaust back pressure

• Improved turbocharger response

• Enhanced power potential

• More efficient engine breathing throughout the operating range

🛡️ ENGINE & TURBINE PROTECTION
The turbine exit experiences the most severe exhaust conditions in the entire system. Enlarging this critical section provides:

• Reduced thermal stress on turbine components

• Lower exhaust gas temperatures

• Improved turbocharger durability

• Enhanced engine protection under high-load conditions

🔧 COMPREHENSIVE KIT INCLUDES O2 SENSOR EXTENSION HARNESS
Understanding that relocation of the oxygen sensor is necessary with this modification, the kit includes the required O2 sensor extension harness for proper installation and functionality.
