aFe POWER Twisted Steel 304 Stainless Steel Long Tube Headers w/ Titanium Ceramic Coating (48-34148-T) - 2020-2026 Chevrolet C8 Corvette
Improve exhaust flow, increase performance, and reduce engine compartment heat in your 2020-2026 Chevrolet C8 Corvette with the aFe POWER Twisted Steel Long Tube Headers with Titanium Ceramic Coating. Featuring a Tri-Y design with optimized tube lengths, these headers deliver dyno-proven gains of up to 17 horsepower and 24 lb-ft of torque while improving exhaust scavenging and flow.
Constructed from mandrel-bent 304 stainless steel, these headers feature an exterior titanium ceramic Cerakote finish and an interior copper ceramic coating. This coating combination reduces header surface temperatures and can lower engine compartment temperatures by as much as 46% compared to uncoated headers. The reduced radiant heat makes this version particularly well suited for C8 Corvette convertible models, where the retracted top is stored above the engine compartment.
Dyno-Proven Performance Gains
The aFe POWER Twisted Steel Long Tube Headers are engineered to improve exhaust flow and 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
Titanium Ceramic Cerakote Coating for Heat Reduction
These headers feature a titanium ceramic Cerakote exterior finish designed to reduce radiant heat from the exhaust system into the engine compartment.
Combined with the interior ceramic coating, this thermal barrier system reduces the outside surface temperature of the headers and can lower engine compartment temperatures by as much as 46% compared to non-coated headers.
This is especially beneficial for C8 Corvette convertible applications, where the convertible top is stored above the engine compartment when lowered. aFe POWER recommends this titanium ceramic-coated version to help reduce heat exposure to the stored convertible top.
Copper Ceramic Interior Coating
In addition to the exterior titanium ceramic coating, the headers feature a copper ceramic coating on the interior surfaces. This coating is designed to improve exhaust flow while working with the exterior finish to help manage exhaust heat.
Mandrel-Bent 304 Stainless Steel Construction
The Twisted Steel headers are manufactured from mandrel-bent 304 stainless steel tubing for strength, durability, and corrosion resistance. Multiple tubing diameters are utilized throughout the Tri-Y configuration to optimize exhaust gas movement.
- 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
- Exterior Finish: Titanium Ceramic Cerakote
- Interior Finish: Copper Ceramic Coating
Optimized Tri-Y Header Design
The Twisted Steel headers feature a Tri-Y configuration with optimized tube lengths and specifically paired opposite-firing cylinders. This design improves cylinder scavenging and exhaust flow to support increased horsepower and torque.
The optimized exhaust routing also produces a powerful exhaust tone while retaining compatibility with the factory catalytic converters.
TIG-Welded Inlet Ports
The header inlet ports feature TIG-welded construction for increased strength and durability. This design helps prevent flange warpage while promoting improved 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. The 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 monitoring location provides flexibility for performance monitoring without requiring modifications to the header tubing.
Retains Factory Sensors and Catalytic Converters
These 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 Tri-Y 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.
