New Arrivals: Best Cat-Back & DPF Delete Systems for F-150, Powerstroke & Duramax Trucks
As vehicle owners seek to optimize engine performance and enhance exhaust efficiency, upgrading the exhaust system has become one of the most effective modifications. Whether you're driving a Ford F-150, a 6.4L Powerstroke, or a 6.6L Duramax, selecting the right Cat-Back or DPF delete system can dramatically improve airflow, reduce exhaust backpressure, lower EGTs (exhaust gas temperatures), and even increase horsepower and fuel efficiency.
DynoVox is proud to introduce five new premium-grade exhaust components engineered for high-performance applications. These products are designed for truck enthusiasts who demand durability, improved performance, and maximum compatibility with popular diesel and gas truck platforms.
1. Cat - Back Exhaust System With Muffler Fit for 2009 - 2014 Ford F - 150 4.6L 5.0L 5.4L
Compatibility and Design
- This cat - back exhaust system is specifically engineered for the 2009 - 2014 Ford F - 150 models equipped with 4.6L, 5.0L, and 5.4L engines. The system features a high - quality muffler that is designed to not only reduce noise but also optimize exhaust flow. The use of premium materials ensures long - term durability, even under harsh driving conditions.
Performance Benefits
- One of the key advantages of this exhaust system is the significant increase in horsepower and torque. By allowing the engine to expel exhaust gases more efficiently, the engine can breathe better, resulting in improved acceleration and overall performance. Additionally, the improved exhaust flow can also lead to better fuel economy, which is a major plus for truck owners who are constantly on the road.
Sound Enhancement
- The muffler in this system is tuned to produce a deep, aggressive growl that gives your F - 150 a more sporty and powerful presence. Whether you're cruising on the highway or revving up at a stoplight, the sound of this exhaust system is sure to turn heads.
2. 5" Downpipe-Back Delete Race Pipe for 2017-2019 Sierra/Silverado L5P 6.6L Duramax
Delete Pipe Function
- The 5" downpipe - back delete race pipe is designed for the 2017 - 2019 Sierra and Silverado trucks with the L5P 6.6L Duramax engine. This pipe eliminates the restrictive factory downpipe and replaces it with a larger-diameter pipe, which greatly improves exhaust flow.
Performance Gains
- With the removal of the factory restrictions, the engine can operate more efficiently, leading to a substantial increase in horsepower and torque. This is especially beneficial for those who use their trucks for towing or hauling heavy loads. The improved exhaust flow also helps to reduce exhaust gas temperatures, which can extend the life of the engine and other components.
Legal Considerations
- It's important to note that in some areas, the use of delete pipes may not be legal for on - road use. However, for off - road or race applications, this pipe can provide a significant performance boost.
3. 4" DPF Delete Race Pipe for 2008 - 2010 Ford F - 250, F - 350 & F - 450 6.4L Powerstroke
DPF Delete Concept
- The Diesel Particulate Filter (DPF) is a component in modern diesel engines that is designed to reduce emissions. However, it can also restrict exhaust flow and cause a decrease in performance. This 4" DPF delete race pipe removes the DPF from the exhaust system, allowing for a more free - flowing exhaust.
Performance Improvements
- By eliminating the DPF, the engine can expel exhaust gases more quickly, resulting in increased horsepower, torque, and improved throttle response. The truck will also experience better fuel efficiency as the engine doesn't have to work as hard to push the exhaust through the system.
Maintenance Advantages
- Without the DPF, there is no need for DPF regeneration cycles, which can be time - consuming and costly. This also reduces the risk of DPF - related problems such as clogging, which can lead to engine damage.
4. DPF Delete Pipe for 2017 - 2024 GMC/Chevrolet 2500HD 3500HD L5P 6.6L Duramax Diesel
Model - Specific Design
- This DPF delete pipe is tailored for the 2017 - 2024 GMC and Chevrolet 2500HD and 3500HD trucks with the L5P 6.6L Duramax diesel engine. It is designed to fit perfectly, ensuring a seamless installation process.
Power and Efficiency
- Similar to the other DPF delete products, this pipe offers a significant increase in power and fuel efficiency. The removal of the DPF allows the engine to reach its full potential, providing a more responsive and powerful driving experience.
Long - Term Durability
- Constructed from high - quality materials, this DPF delete pipe is built to last. It can withstand the high temperatures and pressures of the exhaust system, ensuring reliable performance over time.
5. 3.5 Inch Exhaust Downpipe Fit for 2017-2023 Chevrolet Silverado & GMC Sierra 2500 & 3500HD 6.6L Duramax
Downpipe Upgrade
- The 3.5 - inch exhaust downpipe is an upgrade for the 2017 - 2023 Chevrolet Silverado and GMC Sierra 2500 and 3500HD trucks with the 6.6L Duramax engine. A larger downpipe diameter means less restriction in the exhaust system, allowing for better exhaust flow.
Performance and Emissions
- This downpipe not only improves performance but also has a positive impact on emissions. By reducing backpressure, the engine can burn fuel more efficiently, resulting in lower emissions. This is a win - win situation for both performance enthusiasts and those who are environmentally conscious.
Installation and Compatibility
- The downpipe is designed to be a direct fit for the specified models, making installation relatively straightforward. It is also compatible with other aftermarket performance parts, allowing for further customization of your truck.
- In conclusion, these five new arrivals offer a wide range of benefits for truck owners. Whether you're looking for increased power, better fuel efficiency, or a more aggressive sound, these cat - back and DPF delete systems are sure to meet your needs. However, it's important to check local laws and regulations before making any modifications to your vehicle. So, go ahead and take your truck's performance to the next level with these top - of - the - line exhaust systems.
