The 99-04 Mustang GT. A legend. A classic. And with the right modifications, an absolute powerhouse. One of the most impactful upgrades you can make to unlock serious horsepower and torque is installing long tube headers. But with so many options available, choosing the right set can feel overwhelming. This guide dives deep into the world of long tube headers for your 99-04 Mustang GT, helping you make an informed decision and unleash your car's full potential.

What are Long Tube Headers?

Long tube headers are exhaust manifolds that significantly extend the length of the primary tubes compared to stock manifolds or shorty headers. This design offers several key advantages, primarily maximizing exhaust scavenging and improving engine breathing. Instead of short, restrictive tubes merging close to the engine, long tubes allow exhaust gasses to flow more freely and efficiently, reducing back pressure and increasing horsepower.

Advantages of Long Tube Headers on your 99-04 Mustang GT:

  • Significant Horsepower and Torque Gains: This is the primary reason enthusiasts choose long tube headers. Expect gains in the range of 20-30 horsepower and a noticeable increase in torque, particularly in the mid-range. The exact gains will vary depending on other modifications and the specific header design.

  • Improved Exhaust Flow: The extended length and larger diameter of the primary tubes minimize restrictions, allowing for optimal exhaust gas scavenging. This leads to a more efficient engine breathing cycle.

  • Enhanced Engine Sound: Long tube headers typically produce a more aggressive and throatier exhaust note. This is a subjective benefit, but many Mustang owners appreciate the enhanced sound.

Disadvantages of Long Tube Headers:

  • Potential for Emissions Issues: In some jurisdictions, long tube headers may not meet emissions standards. This is because they can alter the exhaust gas composition, potentially leading to failure of emissions testing. Check your local regulations before installation.

  • Installation Complexity: Installing long tube headers is generally more complex than installing other performance parts. It often requires professional installation or significant mechanical expertise. You may need to modify or replace other components, such as your O2 sensors and exhaust system.

  • Increased Drone at Certain RPMs: The improved exhaust flow can result in increased exhaust drone at certain RPMs, potentially leading to interior noise.

Choosing the Right Long Tube Headers for Your 99-04 Mustang GT:

Selecting the perfect long tube header set involves considering several factors:

  • Material: Stainless steel is the most common material due to its durability and corrosion resistance. Other options include coated steel and ceramic-coated steel, which offer better heat resistance.

  • Tube Diameter: Larger diameter tubes generally offer better flow, but might not be optimal for low-end torque. Finding the right balance is crucial.

  • Collector Design: The collector design, where the primary tubes merge, impacts exhaust flow. Different designs offer varying performance characteristics.

  • Fitment: Ensure the headers are specifically designed for your 99-04 Mustang GT and are compatible with your other modifications (e.g., supercharger, aftermarket engine).

Installation Considerations:

Installing long tube headers typically requires professional expertise due to the complexity involved. Consider these aspects:

  • Exhaust System Compatibility: You'll likely need a new exhaust system designed to work with long tube headers.

  • O2 Sensor Relocation: You may need to relocate or extend your O2 sensors.

  • Tuning: After installation, a professional tune is highly recommended to optimize the engine's performance and prevent potential damage.

Conclusion:

Long tube headers represent a significant upgrade for any 99-04 Mustang GT owner seeking substantial horsepower and torque gains. While there are some considerations, such as installation complexity and potential emissions issues, the performance benefits make them a popular choice among enthusiasts. Careful research and selection, coupled with professional installation and tuning, will ensure you unlock the full potential of your Mustang and enjoy the exhilarating performance improvements. Remember to always check your local regulations regarding emissions compliance before installation.
