Pros and Cons of Buying a Du-Bro 011859006990 Muffler Extension for CAT 699 Engines (40-46)

The Du-Bro 011859006990 muffler extension is a popular aftermarket part designed for Caterpillar 699 engines with models 40 and 46. This part is used to extend the length of the original muffler, reducing exhaust noise and improving the overall performance of the engine. In this article, we will discuss the pros and cons of buying this muffler extension to help you make an informed decision.

1. Reduced noise: The primary reason people purchase muffler extensions is to reduce noise levels. By increasing the length of the muffler, the sound waves have more time and distance to dissipate, resulting in a quieter operating engine.

2. Improved performance: A longer muffler allows for better scavenging of exhaust gases, which can lead to improved engine performance. This can result in increased horsepower and torque, making the engine more efficient.

3. Easy installation: The Du-Bro muffler extension is designed to be a direct bolt-on replacement for the factory muffler. This means that installation is usually straightforward and can be completed in a relatively short amount of time.

4. Durable design: Du-Bro is known for manufacturing high-quality, heavy-duty parts. The muffler extension is made from stainless steel, ensuring it can withstand the rigors of heavy-duty use and harsh environments.

1. Cost: The Du-Bro muffler extension can be more expensive than the factory muffler. While the performance benefits may outweigh the cost for some, it may not be a viable option for those on a tight budget.

2. Potential fitment issues: While the Du-Bro muffler extension is designed to be a direct replacement, there have been reports of fitment issues with certain engine models or configurations. It is essential to ensure that the part is compatible with your specific engine before purchasing.

3. Increased weight: The stainless steel construction of the muffler extension adds weight to the exhaust system. This may not be a significant concern for most applications, but it could impact fuel economy or performance in some cases.

The Du-Bro 011859006990 muffler extension for Caterpillar 699 engines (models 40 and 46) offers several benefits, including reduced noise, improved performance, easy installation, and durability. However, it also comes with potential downsides, such as increased cost, potential fitment issues, and increased weight. Ultimately, the decision to purchase this part depends on your specific needs, budget, and engine configuration. If the benefits outweigh the cons for your application, then the Du-Bro muffler extension could be a worthwhile investment.

Before purchasing the Du-Bro muffler extension, it is crucial to ensure that it is compatible with your engine model and configuration. You can contact Du-Bro or a reputable Caterpillar parts supplier for assistance with this. Additionally, consider the cost, potential fitment issues, and increased weight against the benefits of reduced noise and improved performance.
