Description

These T-304 stainless steel long tube headers are designed for selected Chevrolet Camaro and Chevrolet Chevelle Big Block applications. Current supported fitment includes selected 1968 and 1970-1972 Camaro applications, plus selected 1969 and 1971 Chevelle applications with compatible 396 / 427 / 454 Big Block Chevy V8 configurations.

Built with 1-5/8" primary tubes, 3" collectors, 5/16" CNC-machined head flanges, 18-gauge mandrel-bent tubing, and TIG/MIG-welded construction, these headers are designed to support smoother exhaust flow and help reduce exhaust restriction where properly fitted.

Fitment

Use the table below to confirm the main applications currently supported for this product. The 1968-1972 range used in the product title represents the widest combined year range across Camaro and Chevelle applications. It does not mean that every 1968-1972 Camaro or Chevelle configuration is compatible.

Vehicle Supported Year Engine Reference Fitment Notes
Chevrolet Camaro 1968, 1970-1972 BBC 396 / 427 / 454 Selected Big Block applications. Does not fit 1969 Camaro. Verify engine, trim, steering, transmission, and exhaust clearance before purchase.
Chevrolet Chevelle 1969, 1971 BBC 396 / 427 / 454 Current primary supported years. Other Chevelle years and configurations are not represented as confirmed fitment on this page.
Fitment Note: The title uses the combined 1968-1972 application range because supported Camaro and Chevelle applications occur within that overall period. Always follow the vehicle-specific fitment table rather than assuming continuous fitment across every year.

  • This product is not represented as street legal, CARB-compliant, or emissions-compliant for public-road use unless explicitly stated.

Installation Notes

  • Professional installation is highly recommended.
  • Test fit both headers before final tightening.
  • Verify cylinder head flange alignment, gasket seating, collector connection, steering clearance, and downstream exhaust compatibility before installation.
  • Classic vehicle condition, previous repairs, engine swaps, modified exhaust systems, steering setup, and accessory layout may affect installation.
  • Cutting, welding, fabrication, or additional compatible exhaust components may be required depending on the vehicle and existing exhaust setup.
  • Verify all package contents against the XKV Racing packing list before beginning installation.
  • Inspect all exhaust connections for leaks after installation and recheck accessible fasteners after the initial heat cycles.

Important Compatibility Information

Fitment, clearance, exhaust sealing, sound, drivability, and performance results may vary by vehicle and installation. Contact XKV Racing before ordering if the vehicle year, engine displacement, trim, or configuration is not specifically listed above.

What Does an Exhaust Header Actually Do?

The exhaust header is the first section of the exhaust system and mounts directly to the engine. Its role is to collect exhaust gases from each cylinder and route them into the rest of the exhaust system.

Compared to many factory manifolds, header designs often focus on smoother internal flow and more uniform exhaust routing before gases move downstream.

What You May Notice After Installation

Smoother exhaust flow as engine speed increases

More consistent engine behavior across the RPM range

Improved exhaust routing when paired with other intake or exhaust components

Changes in exhaust tone, depending on system configuration

When This Type of Upgrade Is Typically Considered

Addressing airflow limitations in the factory exhaust manifold

Planning coordinated intake or exhaust system updates

Replacing aging or restrictive original components

Build a balanced, performance-focused setup

Factory Manifold vs. Performance Header

Factory Exhaust Manifold

Designed to meet packaging, cost, and emissions requirements
Prioritizes durability and compliance across broad use cases

Performance Exhaust Header

Designed with exhaust flow characteristics in mind
Built for higher exhaust temperatures and specific vehicle platforms
Commonly used as part of an exhaust system configuration

Important Notice

Products on this site are intended for off-road, racing, or closed-course use where emissions laws apply. They are not represented as street legal, emissions-compliant, or legal for use on public roads unless explicitly stated.

Some products may remove, replace, relocate, disable, or alter emissions-related components, including but not limited to catalytic converters, EGR, DPF, SCR, DOC, O2 sensors, or related factory systems. Compatible tuning, calibration, or supporting modifications may be required to avoid engine codes or drivability issues.

Professional installation is recommended. Buyers are responsible for verifying product compatibility, local regulations, emissions requirements, and any required tuning or supporting modifications before purchase and installation.

Performance gains, sound changes, airflow improvements, temperature changes, fuel economy changes, fitment, and drivability results may vary. No specific performance gains are guaranteed.

Frequently Asked Questions

What do exhaust headers do? +

Exhaust headers help route exhaust gases away from the engine through individual tubes and collector-style routing. Actual results depend on the vehicle, engine condition, exhaust system, installation quality, and supporting components.

What's the difference between headers and factory manifolds? +

Factory manifolds are typically designed around packaging, durability, emissions requirements, and production cost. Headers or manifold-related exhaust upgrades may use different tube routing, flange designs, or connection layouts depending on the application.

Will headers increase horsepower? +

Headers may support improved exhaust flow where the product is compatible, but horsepower and torque changes are not guaranteed. Results vary by engine setup, tuning, exhaust configuration, vehicle condition, installation, and supporting modifications.

Do headers make the vehicle louder? +

Headers and related exhaust parts can change exhaust tone and may increase sound depending on the rest of the exhaust system. Final sound level depends on the engine, mufflers, catalytic converters, pipe routing, and complete exhaust setup.

Do I need tuning after installing headers? +

Tuning requirements depend on the vehicle, engine management system, O2 sensor setup, emissions equipment, and supporting modifications. Some installations may not require tuning, while modified builds may require professional inspection, calibration, or tuning to support proper drivability.

Are header products street legal? +

Header and exhaust products may be intended for off-road or racing use where emissions laws apply. They are not represented as street legal, emissions-compliant, or CARB-compliant for public road use unless a valid exemption is explicitly stated. Always check local regulations before purchase and installation.

Can I use headers with a stock exhaust system? +

Compatibility with a stock exhaust system depends on the vehicle and existing exhaust configuration. Some vehicles may require additional hardware, gaskets, connectors, adjustment, or fabrication to complete installation.

Are headers hard to install? +

Installation difficulty varies by vehicle. Tight engine bays, old hardware, rust, engine swaps, modified exhaust systems, sensor placement, and clearance around surrounding components can increase installation complexity. Professional installation is recommended.

Will headers affect reliability? +

Reliability depends on fitment accuracy, installation quality, vehicle condition, heat management, gasket sealing, fastener condition, sensor placement, and supporting components. Proper inspection and installation are important.
