The roar of a Mustang GT is music to many car enthusiasts' ears, and upgrading to long tube headers is a popular modification to amplify that sound and boost performance. But what exactly are long tube headers, and are they right for your Mustang GT? This comprehensive guide will explore everything you need to know about long tube headers for your Mustang GT, from the performance gains to the potential downsides.
What are Long Tube Headers?
Long tube headers are exhaust manifolds that extend significantly further down the chassis than shorty headers or stock manifolds. This longer design allows for improved scavenging, which means the exhaust gases are more efficiently extracted from the engine's cylinders. This improved scavenging leads to increased horsepower and torque, especially in the mid to upper RPM range. They fundamentally change how the exhaust system works, optimizing the flow of gases.
What are the Benefits of Long Tube Headers on a Mustang GT?
The primary advantage of installing long tube headers on your Mustang GT is a noticeable increase in horsepower and torque. This improvement stems from the increased exhaust gas velocity and reduced back pressure. The longer tubes allow for a more efficient scavenging effect, pulling exhaust gases out of the cylinders more effectively. This results in better volumetric efficiency, meaning more air and fuel can enter the cylinders on the intake stroke.
- Increased Horsepower and Torque: Expect a substantial increase in power, typically ranging from 20 to 50 horsepower, depending on other modifications and the specific header design.
- Improved Throttle Response: The reduced back pressure leads to a more responsive throttle, enhancing the driving experience and making the car feel more alive.
- Enhanced Exhaust Note: The signature deep, throaty rumble associated with long tube headers is a significant draw for many Mustang GT owners. The sound is undeniably more aggressive and powerful.
What are the Drawbacks of Long Tube Headers on a Mustang GT?
While the benefits are substantial, it's crucial to be aware of the potential drawbacks:
- Emissions: Long tube headers often result in failed emissions tests, as they drastically alter the exhaust flow and can increase the levels of certain pollutants. This is particularly relevant in areas with strict emission regulations.
- Installation Complexity: Installation is more involved than swapping shorty headers and often requires professional installation, potentially increasing the overall cost. This can include cutting and welding.
- Potential Drone: The improved exhaust note can come with a noticeable drone at certain RPM ranges, which some drivers find annoying, particularly on long highway drives.
- Check Engine Light: You may trigger a check engine light due to the altered exhaust system. An aftermarket tune is often necessary to address this.
- Ground Clearance: The long tubes may lower the ground clearance of your vehicle, increasing the risk of damage when driving over uneven surfaces or speed bumps.
What are the different types of long tube headers?
There's a variety of long tube headers available, each with its own design and performance characteristics. Some are made from stainless steel for durability, others from ceramic-coated materials for better heat management. The tube diameter, material, and collector design all influence the performance and sound.
Do I need a tune after installing long tube headers?
Yes, generally you will need a professional tune after installing long tube headers. This tune will calibrate the engine's computer to compensate for the changes in airflow and exhaust flow, ensuring optimal performance and preventing potential engine damage. Failing to get a proper tune can negatively affect performance and potentially damage your engine.
How much do long tube headers cost for a Mustang GT?
The cost of long tube headers varies greatly depending on the brand, material, and features. Expect to pay anywhere from several hundred dollars to over a thousand dollars for a quality set. The cost of installation should also be factored into your budget.
Are long tube headers street legal?
The legality of long tube headers varies greatly depending on your location and local emission regulations. In some areas they may be perfectly legal, while in others they could result in fines or failed emissions inspections. Always check your local regulations before installation.
Conclusion: Weighing the Pros and Cons
Long tube headers offer a compelling upgrade for the Mustang GT, providing significant performance gains and a unique exhaust note. However, it's essential to carefully weigh the potential drawbacks, including the complexity of installation, potential emissions issues, and the possibility of a check engine light. Consider your budget, local regulations, and your driving style before making a decision. Thorough research and professional guidance are crucial for a successful and satisfying installation.
