aFe POWER Twisted Steel 304 Stainless Steel Long Tube Headers w/ Brushed Finish (48-34148-H) - 2020-2026 Chevrolet C8 Corvette
Improve exhaust flow and performance in your 2020-2026 Chevrolet C8 Corvette 6.2L V8 with the aFe POWER Twisted Steel Long Tube Headers with Brushed Stainless Steel Finish. Featuring an optimized Tri-Y design, mandrel-bent 304 stainless steel tubing, and 100% TIG-welded construction, these headers deliver dyno-proven gains of up to 17 horsepower and 24 lb-ft of torque.
The brushed stainless steel finish provides a distinctive appearance while maintaining excellent corrosion resistance. Designed to retain factory catalytic converters and sensors, these headers offer improved exhaust performance with direct bolt-on installation.
Dyno-Proven Performance Gains
The aFe POWER Twisted Steel Long Tube Headers are engineered to improve exhaust scavenging and increase engine performance. Testing on aFe POWER's in-house dynamometer demonstrated gains of up to 17 horsepower and 24 lb-ft of torque.
- Horsepower Gain: Up to 17 HP
- Torque Gain: Up to 24 lb-ft
Mandrel-Bent 304 Stainless Steel Construction
These headers are constructed from mandrel-bent 304 stainless steel tubing for strength, durability, and corrosion resistance. The system incorporates three tubing diameters to support its optimized Tri-Y configuration.
- Primary Tubing Diameter: 1-7/8 Inches
- Secondary Tubing Diameter: 2-1/8 Inches
- Collector Tubing Diameter: 2-3/4 Inches
- Material: 304 Stainless Steel
- Finish: Brushed Stainless Steel
The mandrel-bent tubing maintains smooth exhaust passages to promote efficient exhaust flow.
Premium Brushed Stainless Steel Finish
The Twisted Steel headers feature a brushed finish on the 304 stainless steel tubing, providing a distinctive appearance that complements the C8 Corvette's performance-focused design.
The brushed stainless steel construction offers corrosion resistance without requiring an additional exterior coating.
Optimized Tri-Y Header Design
The Tri-Y configuration features optimized tube lengths and specifically paired opposite-firing cylinders to improve cylinder scavenging and exhaust flow.
This design is engineered to support increased horsepower and torque while producing a powerful exhaust tone.
100% TIG-Welded Construction
These headers feature 100% TIG-welded construction for strength and durability. The TIG-welded inlet ports are designed to help prevent flange warpage while improving exhaust flow through the inlet passages.
Laser-Cut 304 Stainless Steel Flanges
Factory-style laser-cut 304 stainless steel flanges provide precise alignment and a secure, leak-free seal. These flanges are designed to work with the factory mounting locations and included gaskets.
Auxiliary O2 Sensor Bung
The headers include an auxiliary oxygen sensor bung and plug for installation of a wideband O2 sensor or other compatible instrumentation.
This additional sensor location provides flexibility for exhaust monitoring without requiring modifications to the header tubing.
Retains Factory Sensors and Catalytic Converters
The Twisted Steel headers are designed to retain all factory sensors and remain compatible with the original catalytic converters.
This allows the system to maintain factory sensor connections while benefiting from the improved exhaust flow characteristics of the long tube header design.
Direct Bolt-On Installation
Using computer-aided design technology, aFe POWER engineered these headers for precise, high-tolerance factory fitment.
The system includes manifold bolts and factory gaskets for direct bolt-on installation. No cutting or vehicle modifications are required on compatible applications.
aFe POWER exhaust systems are engineered and manufactured at the company's facility in Corona, California.

Important Fitment and Installation Notes
E-Ray Exclusion: These headers do not fit Chevrolet Corvette E-Ray models.
Convertible Models: Part number 48-34148-H will physically fit compatible C8 Corvette convertible models but is not recommended by aFe POWER for these applications. For convertibles, aFe POWER recommends the titanium ceramic-coated version, part number 48-34148-T, due to its reduced radiant heat in the engine compartment.
Factory Components: The system retains factory sensors and catalytic converters. Manifold bolts and factory gaskets are included for direct bolt-on installation.
Emissions Disclaimer: Some or all listed applications are 50-state emissions exempt under CARB Executive Order D-550-49. Refer to the applicable CARB EO documentation to verify that your specific vehicle and model year are covered.
