Proven Performance Gains
The aFe Twisted Steel Headers are engineered to maximize the performance potential of the C8 Corvette Stingray's naturally aspirated LT2 engine.
By improving exhaust flow and cylinder scavenging, these headers help the engine expel exhaust gases more efficiently.
Manufacturer-Reported Performance Gains:

Horsepower: Up to +24 HP

Torque: Up to +17 lb-ft

Actual performance gains may vary depending on vehicle configuration, supporting modifications, and testing conditions.
Advanced Tri-Y Header Design
Unlike conventional exhaust manifold designs, the aFe Twisted Steel Headers utilize a Tri-Y configuration with carefully optimized tube lengths.
The design pairs opposite-firing cylinders to improve exhaust pulse management and cylinder scavenging.
This helps reduce exhaust interference and promotes more efficient exhaust flow throughout the engine's operating range.
The system utilizes multiple tubing diameters:

1-7/8" Primary Tubing

2-1/8" Secondary Tubing

2-3/4" Collector Tubing

Each section is engineered to support efficient exhaust gas movement while maintaining strong performance characteristics.
Premium 304 Stainless Steel Construction
Manufactured from mandrel-bent 304 stainless steel, these headers are built for durability, strength, and corrosion resistance.
Additional construction features include:

TIG-welded inlet ports to improve exhaust flow and minimize flange distortion

Laser-cut stainless steel flanges for precise mounting

Smooth mandrel bends to maintain consistent internal tubing diameter

Durable construction designed for demanding performance applications

OEM Catalytic Converter Compatibility
The aFe Twisted Steel Headers are designed to work with the factory C8 Corvette Stingray catalytic converters, eliminating the need to replace the OEM catalytic converter assemblies solely to install the headers.
The system also retains compatibility with the factory oxygen sensors.
An additional O2 sensor bung and plug are included for owners who want to install a wideband oxygen sensor or other monitoring equipment.
Available Finishes
Choose the finish that best suits your build:

Raw Stainless Steel

Brushed Stainless Steel

Titanium Ceramic Coated

Finish availability may vary.
Installation
The aFe Twisted Steel Headers are designed as a bolt-on replacement for the factory exhaust manifolds.
The kit includes the necessary manifold bolts and factory-style gaskets for installation.
Estimated Installation Time: 5 Hours
Installation Difficulty: Moderate to Difficult
Professional installation is recommended due to the limited engine-bay access and exhaust system complexity of the mid-engine C8 Corvette.
Why You Need This
The factory C8 Corvette Stingray delivers impressive performance, but upgrading the restrictive OEM exhaust manifolds is an excellent way to unlock additional potential from the LT2 V8.
The aFe Power Twisted Steel Headers combine a performance-focused Tri-Y design with premium stainless steel construction to deliver up to 24 additional horsepower and 17 lb-ft of torque.
Unlike header systems that require aftermarket catalytic converters, these retain compatibility with the factory catalytic converters and oxygen sensors, making them a practical performance upgrade for owners looking to improve exhaust flow without replacing the entire exhaust system.
Whether you're building a street-focused Stingray or a more aggressive performance setup, these headers provide a strong foundation for additional exhaust upgrades.
