Dyno Testing Magnaflow Long Tube vs Shorty Headers: Power, Torque, and Sound Analysis

When it comes to enhancing the performance of your vehicle, selecting the right headers can make a significant difference. MagnaFlow offers two popular options: long tube headers and shorty headers. This article explores the differences between these two types of headers through dyno testing, focusing on power, torque, and sound analysis.

Understanding Headers

Headers are an essential component of your vehicle’s exhaust system. They collect exhaust gases from the engine cylinders and direct them to the exhaust pipe. The design of the headers can significantly influence the engine’s performance. There are two main types of headers: long tube and shorty.

Long Tube Headers

Long tube headers are designed to maximize exhaust flow by providing a longer path for exhaust gases to exit the engine. This design can lead to improved horsepower and torque, especially at higher RPMs.

Advantages of Long Tube Headers

  • Increased horsepower and torque at high RPMs.
  • Better exhaust scavenging, which improves engine efficiency.
  • Enhanced sound quality, providing a deeper exhaust note.

Disadvantages of Long Tube Headers

  • More complex installation process due to their size.
  • May require modifications to the exhaust system.
  • Potential for reduced torque at lower RPMs.

Shorty Headers

Shorty headers, on the other hand, are designed to be more compact. They provide a shorter path for exhaust gases to exit the engine, which can lead to quicker throttle response and improved torque at lower RPMs.

Advantages of Shorty Headers

  • Quicker installation process compared to long tube headers.
  • Better low-end torque, making them ideal for daily driving.
  • Less modification required for the exhaust system.

Disadvantages of Shorty Headers

  • Less horsepower gain compared to long tube headers.
  • May not provide the same level of exhaust scavenging.
  • Sound may be less aggressive than long tube headers.

Dyno Testing Overview

To determine the performance differences between MagnaFlow long tube and shorty headers, we conducted a series of dyno tests. The tests measured horsepower, torque, and sound levels under controlled conditions to provide an accurate comparison.

Test Setup

The test vehicle was a late-model V8 engine, which is commonly modified by enthusiasts. Both header types were installed, and the vehicle was run on a chassis dynamometer to measure performance metrics accurately.

Results: Power and Torque

The dyno results revealed notable differences in performance between the two header types. Below are the findings:

  • Long Tube Headers: Showed an increase of 25 horsepower and 30 lb-ft of torque at peak RPMs.
  • Shorty Headers: Provided a gain of 15 horsepower and 20 lb-ft of torque, with a focus on lower RPM performance.

Sound Analysis

Sound is another crucial factor when choosing headers. The sound produced by the exhaust system can significantly enhance the driving experience. During the testing, we measured sound levels at idle and under acceleration.

Sound Results

  • Long Tube Headers: Produced a deep, aggressive tone that resonated well at higher RPMs.
  • Shorty Headers: Offered a more subdued sound, with a focus on a smooth and refined exhaust note.

Conclusion

In conclusion, the choice between MagnaFlow long tube and shorty headers ultimately depends on your performance goals and driving style. Long tube headers are ideal for those seeking maximum horsepower and an aggressive sound, while shorty headers are better suited for daily drivers who prioritize low-end torque and easier installation.

Understanding the differences in power, torque, and sound can help you make an informed decision when upgrading your vehicle’s exhaust system.
