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 unleash more power. But what exactly are long tube headers, and are they the right choice for your Mustang GT? This comprehensive guide dives deep into the world of long tube headers, exploring their benefits, drawbacks, and everything in between.
What are Long Tube Headers?
Long tube headers are exhaust system components that replace the factory manifolds. Unlike shorty headers or mid-length headers, long tube headers extend significantly further down the chassis, usually all the way past the front axle. This extended length allows for a more efficient scavenging effect, significantly improving exhaust flow. This improved flow translates directly into increased horsepower and torque, particularly in the higher RPM ranges.
Benefits of Long Tube Headers on a Mustang GT
The advantages of installing long tube headers on your Mustang GT are numerous:
-
Significant Horsepower and Torque Gains: The primary benefit is a noticeable increase in horsepower and torque. The improved exhaust scavenging allows for a more complete evacuation of exhaust gases, resulting in a more efficient combustion process. Expect gains in the range of 20-40 horsepower and a similar increase in torque, depending on other modifications and the specific header design.
-
Improved Engine Sound: Long tube headers dramatically alter the engine's sound. The longer tubes and increased exhaust flow produce a deeper, more aggressive exhaust note, often described as more throaty and powerful. This is a major draw for many Mustang GT owners.
-
Increased Throttle Response: Improved exhaust flow directly translates to quicker throttle response. The engine reacts more readily to the accelerator pedal, providing a more exhilarating driving experience.
Drawbacks of Long Tube Headers on a Mustang GT
While the benefits are substantial, it's crucial to acknowledge the potential downsides:
-
Potential for Emissions Issues: Long tube headers can sometimes lead to issues with emissions testing, as they can alter the exhaust gas composition. This is especially important to consider if you live in an area with strict emissions regulations.
-
Installation Complexity: Installing long tube headers is generally more complex than installing other exhaust modifications. It often requires professional installation, which can add to the overall cost.
-
Potential for Reduced Low-End Torque: While long tube headers provide significant gains in the upper RPM range, they can sometimes slightly reduce low-end torque. This may be less noticeable in street driving but can be more pronounced on the track.
-
Ground Clearance Issues: The extended length of long tube headers can potentially reduce ground clearance, making them less suitable for vehicles frequently traversing uneven terrain.
-
Cost: Long tube headers represent a significant investment compared to other exhaust upgrades. The cost varies greatly depending on the brand and material (stainless steel or ceramic coated).
What size long tube headers should I get for my Mustang GT?
The ideal header size depends on several factors, including your engine modifications, driving style, and desired performance characteristics. Larger diameter headers generally flow better at higher RPMs, resulting in increased horsepower at the expense of low-end torque. Smaller diameter headers may offer better low-end torque but sacrifice some high-end power. Consulting with an experienced performance shop can help determine the optimal header size for your specific setup.
Are long tube headers street legal?
The legality of long tube headers varies significantly by location and often depends on whether the headers are CARB-compliant. Some areas have stricter emissions regulations than others, and installing non-compliant headers could result in failing emissions tests or even fines. Always check your local regulations before purchasing and installing long tube headers.
Will long tube headers void my warranty?
Installing aftermarket parts like long tube headers can potentially void your vehicle's warranty, especially if the modification causes damage to the engine or other components. However, this largely depends on the dealership and the specific terms of your warranty. It’s advisable to consult your warranty documentation or your dealership before undertaking this modification.
Conclusion
Long tube headers offer a potent performance upgrade for the Mustang GT, delivering significant horsepower and torque gains along with a more aggressive exhaust note. However, careful consideration of the potential drawbacks, including installation complexity, emissions implications, and cost, is crucial before making the investment. Weighing the pros and cons and understanding your local regulations will help you make an informed decision that aligns with your driving style and performance goals. Ultimately, the decision comes down to your priorities and budget.
