Fitment Note: This is an application-specific Mopar Big Block header set, not a universal header. Verify the actual engine installed in the vehicle, year, model, existing exhaust connection and available engine-bay clearance before purchase.

Important: 1966 Chrysler New Yorker is not included in the listed fitment.

Installation & Fitment Notes

Before Installation

  • Confirm the vehicle year, model and actual installed engine.
  • Compare the supplied header flange and exhaust connection with the existing setup.
  • Check clearance around the steering system, starter, frame, suspension and engine mounts.
  • Inspect surrounding spark plug and exhaust-system clearance before final installation.

Installation Notes

  • Professional installation is recommended.
  • Test fit the complete header assembly before final tightening.
  • Classic vehicles with engine swaps or previous modifications may require additional adjustment or fabrication.
  • Additional gaskets, fasteners or exhaust-side hardware may be required depending on the existing setup.
  • Recheck and retighten fasteners after initial heat cycles where appropriate.

Package & Product Check

Package Includes

  • Shorty exhaust header set
  • Mounting hardware as supplied

Before Starting Installation

  • Compare all supplied components with the product photos.
  • Confirm required gaskets, bolts and exhaust connectors before installation.
  • Do not complete final tightening until fitment and clearance have been verified.

Before You Buy

  • Designed for the selected 1959-1978 Chrysler, Plymouth and Dodge Mopar Big Block applications listed above.
  • Core product positioning is for 383, 400 and 440 Mopar Big Block applications; use the complete vehicle table to confirm the exact engine displacement for your vehicle.
  • Does not fit the 1966 Chrysler New Yorker application.
  • This is an application-specific shorty header set, not a universal Mopar header.
  • Classic vehicles may have engine swaps, aftermarket steering, modified engine mounts or custom exhaust systems that affect installation clearance.
  • Verify year, model, actual engine, flange configuration, exhaust connection and installation clearance before ordering.

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.
