The Ford Mustang GT. A legend. A muscle car icon. But even legends can be improved, and for those seeking to unlock even more power and that signature throaty roar, long tube headers are a popular upgrade. This in-depth guide will explore everything you need to know about long tube headers for your Mustang GT, from the performance gains to the potential downsides, helping you make an informed decision.

What are Long Tube Headers?

Long tube headers are a performance modification that replaces your vehicle's stock exhaust manifolds. Unlike shorty headers, which are relatively short and close to the engine, long tube headers extend further down and away from the engine block, often exiting near the axle or even further back. This longer path allows for improved scavenging—the process of efficiently extracting exhaust gases from the cylinders.

Performance Benefits of Long Tube Headers on a Mustang GT

The key benefit of long tube headers is increased horsepower and torque. By optimizing exhaust flow, they allow the engine to breathe more easily, leading to significant performance gains, particularly in the mid-to-upper RPM range. You can expect noticeable improvements in:

Horsepower: Significant gains are achievable, often in the range of 20-40 horsepower, depending on other modifications and the specific header design.
Torque: While not as dramatic as the horsepower gains, torque increases are still noticeable, contributing to improved acceleration and throttle response.
Exhaust Note: The most immediately noticeable change is the sound. Long tube headers produce a deeper, more aggressive exhaust note, a hallmark of high-performance Mustangs.

Understanding the Science Behind the Gains

The increased performance isn't just magic; it's physics. The longer tubes allow for a more efficient scavenging effect, reducing exhaust backpressure. Less backpressure means the engine can expel exhaust gases more quickly, allowing for quicker intake of the fresh air-fuel mixture. This improved breathing translates directly to more power.

Considerations Before Installing Long Tube Headers

While the performance benefits are undeniable, there are several factors to consider before installing long tube headers on your Mustang GT:

Potential Downsides:

Emissions: Long tube headers can negatively impact emissions, potentially resulting in a failure of emissions testing in areas where it's mandated.
Installation Complexity: Installation is generally more complex than other bolt-on modifications. Professional installation is often recommended due to the potential for interference with other components.
Cost: Long tube headers are a significant investment, often costing several hundred to over a thousand dollars, depending on the brand and material.
Tuning Requirements: For optimal performance and to avoid potential issues, professional tuning after installation is usually recommended. This is especially important to prevent running lean and damaging your engine.
Ground Clearance: Depending on the header design and your Mustang's modifications, ground clearance might be reduced.

Choosing the Right Long Tube Headers

The market offers a wide variety of long tube headers for the Mustang GT, made from different materials (stainless steel, coated steel) and with various designs. Consider factors like:

Material: Stainless steel offers superior corrosion resistance but is generally more expensive.
Design: Different designs offer varying performance characteristics and levels of ground clearance.
Brand Reputation: Choose reputable brands with a proven track record of quality and performance.
Compatibility: Ensure the headers are compatible with your specific year and model of Mustang GT and any other modifications you have.

Conclusion: Making the Right Choice

Long tube headers offer significant performance gains for the Mustang GT, but they're not a one-size-fits-all solution. Carefully weigh the benefits and drawbacks, consider your budget and mechanical skills, and choose a reputable installer if you're not comfortable with the installation yourself. With careful planning and execution, long tube headers can transform your Mustang GT into a true powerhouse. Remember to always prioritize safe driving practices and follow all local regulations.
