The roar of a Mustang GT is music to many car enthusiasts' ears, and upgrading to long tube headers is a popular modification to enhance that sound and performance. But what exactly are long tube headers, and are they right for your Mustang GT? This comprehensive guide will delve into everything you need to know about long tube headers for your Mustang GT, addressing common questions and concerns.

What are Long Tube Headers?

Long tube headers are exhaust system components that replace the factory manifolds. Unlike shorty headers, which are shorter and often less restrictive, long tube headers extend further down the chassis, typically exiting near the axle. This extended length allows for a more efficient scavenging effect, improving exhaust gas flow and reducing back pressure. This translates to increased horsepower and torque, particularly in the mid-to-upper RPM range.

What are the Benefits of Long Tube Headers on a Mustang GT?

The primary benefit of installing long tube headers on your Mustang GT is a significant horsepower and torque increase. The improved exhaust scavenging reduces back pressure, allowing the engine to breathe more easily and produce more power. You can expect gains ranging from 20-40 horsepower, depending on the specific headers, engine modifications, and tuning.

Beyond horsepower gains, long tube headers often contribute to a more aggressive and throatier exhaust note. This enhanced sound is a major draw for many Mustang owners seeking to personalize their car's auditory experience.

However, it's crucial to understand that these performance gains often come with trade-offs, which we'll explore later.

Are Long Tube Headers Street Legal?

This is a crucial question with no simple yes or no answer. The legality of long tube headers varies significantly depending on your location and specific vehicle emission regulations. Many areas require vehicles to pass emissions testing, and long tube headers can often fail these tests due to their impact on emissions readings. Some states are stricter than others. Additionally, the presence of catalytic converters (and their efficiency) plays a role in legality. It's essential to check your local and state regulations before purchasing and installing long tube headers. Modifying your exhaust system to fail emissions standards could result in fines or even the failure of your vehicle inspection.

Will Long Tube Headers Void My Warranty?

Installing aftermarket parts like long tube headers almost certainly voids any remaining factory warranty covering the affected engine components. Manufacturers often stipulate that modifications invalidate the warranty if a component failure can be directly linked to the aftermarket part. Consult your vehicle's warranty documentation and dealer for precise details.

Do I Need a Tune After Installing Long Tube Headers?

Yes, absolutely. Installing long tube headers significantly alters your Mustang GT's air-fuel ratio and engine parameters. Running the engine without a proper tune after installing long tube headers can lead to poor performance, potential engine damage, and possibly even catastrophic failure. A custom tune is essential to optimize the engine's performance and safety after the modification.

What are the Drawbacks of Long Tube Headers?

While the performance gains are enticing, long tube headers are not without drawbacks:

  • Emissions: As mentioned above, they can negatively impact emissions readings.
  • Lower RPM Torque: While boosting high-RPM power, they might slightly reduce low-RPM torque, making city driving feel slightly less responsive.
  • Cost: Long tube headers are a significant investment, often costing several hundred dollars.
  • Installation: Professional installation is often recommended, adding to the overall expense.
  • Potential for Ground Clearance Issues: The extended length can reduce ground clearance, potentially causing scraping on uneven roads or speed bumps.

Choosing the Right Long Tube Headers for Your Mustang GT

The market offers a wide variety of long tube headers from different manufacturers. Factors to consider when choosing include material (stainless steel is common), fitment (ensure compatibility with your specific year and model), and price. Researching reviews and comparing specifications from reputable brands is crucial before making a purchase.

In conclusion, long tube headers can dramatically improve your Mustang GT's performance, but careful consideration of the legal, mechanical, and financial implications is paramount. Thorough research, professional installation, and a proper tune are key to maximizing the benefits and minimizing potential risks.
