Paccar M11-6539 Bracket-Exhaust Dual BOS: A Comprehensive Analysis

The Paccar M11-6539 bracket-exhaust dual BOS (behind-the-back exhaust) is a popular aftermarket addition for Paccar trucks, particularly Kenworth and Peterbilt models. This system offers several advantages, but it also comes with some potential disadvantages. In this analysis, we will discuss both sides to help you make an informed decision.

1. Aerodynamics: The primary advantage of a dual BOS is improved aerodynamics. The exhaust system is mounted behind the cab, reducing the overall frontal area of the truck. This leads to reduced air resistance, lower wind noise, and improved fuel efficiency.

2. Engine Performance: A dual BOS can also enhance engine performance by reducing backpressure and improving exhaust gas flow. This leads to increased power and torque, particularly noticeable at high altitudes or in heavy-load applications.

3. Appearance: Many truck enthusiasts consider the dual BOS to be a desirable aesthetic upgrade. The system hides the exhaust stacks behind the cab, giving the truck a cleaner, more streamlined look.

4. Maintenance: With a dual BOS, the exhaust stacks are easier to access for maintenance, as they are not located under the cab. This makes inspections and repairs more convenient and less time-consuming.

1. Cost: The primary disadvantage of a dual BOS is the cost. The system is more expensive than a traditional under-cab exhaust system. Additionally, the installation process can be more complex, requiring specialized labor and tools.

2. Weight: The dual BOS adds weight to the truck, which can negatively impact fuel efficiency, particularly for long-haul applications. However, the weight difference is relatively small and may be offset by the aerodynamic benefits and improved engine performance.

3. Installation Complexity: The installation process for a dual BOS can be more complex than a standard exhaust system. It requires the modification of the truck's frame and the fabrication of custom brackets. This can make the installation process more time-consuming and costly.

The Paccar M11-6539 bracket-exhaust dual BOS offers several advantages, including improved aerodynamics, enhanced engine performance, a more streamlined appearance, and easier maintenance. However, the system also comes with some disadvantages, such as a higher cost, increased weight, and a more complex installation process.

If you prioritize fuel efficiency, a standard under-cab exhaust system may be a better choice. However, if you value the improved engine performance, aerodynamics, and appearance of a dual BOS, the additional cost and complexity may be worth it. Ultimately, the decision comes down to your personal preferences and priorities.

If you are considering a Paccar M11-6539 bracket-exhaust dual BOS, we recommend doing thorough research and consulting with a reputable truck parts supplier or installation specialist. They can help you assess the potential benefits and drawbacks for your specific application and provide guidance on the installation process. Additionally, be prepared for a higher upfront cost and potential installation complications.
