The roar of a Mustang GT is music to many car enthusiasts' ears. But for those seeking to truly unleash the power hidden beneath the hood, upgrading to long tube headers is a popular modification. This comprehensive guide delves into everything you need to know about long tube headers for your Mustang GT, from performance gains to installation considerations. We'll also tackle some frequently asked questions to help you make an informed decision.
What are Long Tube Headers?
Long tube headers are a performance upgrade that replaces your vehicle's factory exhaust manifolds. Unlike shorty headers which remain close to the engine, long tube headers extend further down, often exiting near the chassis or even further back. This longer path allows for improved scavenging – a more efficient evacuation of exhaust gases – leading to increased horsepower and torque. The increased exhaust flow also reduces backpressure, allowing the engine to breathe more freely.
What are the Performance Gains of Long Tube Headers on a Mustang GT?
The benefits of installing long tube headers on a Mustang GT are substantial. You can expect a noticeable increase in horsepower and torque, especially in the mid-to-upper RPM range. While the exact gains depend on factors like engine modifications, the overall setup, and even the specific header brand and design, it's not uncommon to see gains in the range of 20-40 horsepower and a similar increase in torque. This translates to improved acceleration, a more aggressive sound, and a more exhilarating driving experience.
Will Long Tube Headers Affect My Car's Emissions?
Yes, long tube headers typically cause a vehicle to fail emissions testing. This is because they significantly alter the exhaust system's design, affecting the way emissions are processed. The modified exhaust flow can disrupt the catalytic converter's function, potentially leading to higher emissions. Before installing long tube headers, research your local emission regulations and consider if you’ll need to install high-flow catalytic converters or other emission-compliant components to pass inspection.
Do I Need a Tune After Installing Long Tube Headers?
Absolutely. Installing long tube headers significantly alters the air-fuel ratio and exhaust flow. Without a proper tune, your engine's computer will be unable to compensate for these changes, potentially leading to poor performance, engine damage, or even a check engine light. A custom tune is essential to optimize the engine's performance and ensure its safe and reliable operation after the header installation.
Are Long Tube Headers Street Legal?
The legality of long tube headers varies significantly depending on your location and local regulations. Some areas have stricter emission standards and might prohibit the use of long tube headers without additional modifications to bring emissions back within acceptable ranges. Always check with your local Department of Motor Vehicles (DMV) or equivalent authority to understand the regulations in your area.
What About the Sound?
One of the most noticeable effects of installing long tube headers is the change in exhaust sound. The improved scavenging and freer-flowing exhaust system typically results in a deeper, more aggressive, and louder exhaust note. This is a significant selling point for many Mustang GT owners seeking a more muscular sound. However, it's important to be aware that the increased volume may not be suitable for everyone or in all driving situations.
How Difficult is the Installation Process?
Installing long tube headers is generally considered a moderately difficult project requiring mechanical aptitude and some specialized tools. The process typically involves removing the factory manifolds, installing the new headers, connecting the exhaust system, and potentially dealing with oxygen sensor relocation. This process often requires dropping the transmission or other significant components. Most owners choose professional installation to avoid any complications.
What Brands of Long Tube Headers are Recommended for Mustang GTs?
The market offers several reputable brands specializing in long tube headers for Mustang GTs. Researching reviews and comparing specifications will help you choose the best option for your specific needs and budget. Remember, header fitment and quality can vary between manufacturers and even specific model years. Thorough research and reading reviews is critical.
This detailed guide provides a comprehensive overview of Mustang GT long tube headers. Remember to always prioritize safety and legality when modifying your vehicle. Consult with professionals for installation and tuning, and thoroughly research your local regulations before proceeding.
