The 6.7 Power Stroke engine is a powerhouse, but unleashing its full potential often requires upgrades. A 5-inch turbo-back exhaust system is a popular modification among Ford Power Stroke owners looking to boost performance, improve sound, and increase fuel efficiency. This comprehensive guide explores everything you need to know about a 5-inch turbo-back exhaust for your 6.7 Power Stroke, answering common questions and providing valuable insights.
What are the Benefits of a 5-Inch Turbo Back Exhaust?
A 5-inch turbo-back exhaust system offers several advantages over the factory setup. The larger diameter pipe significantly reduces exhaust backpressure, allowing for increased airflow. This leads to several key benefits:
- Increased Horsepower and Torque: Reduced backpressure means the engine can breathe more freely, resulting in noticeable gains in horsepower and torque across the RPM range. This translates to improved acceleration and towing capabilities.
- Improved Fuel Efficiency: By optimizing exhaust flow, a 5-inch turbo-back system can lead to slightly better fuel economy, especially under heavy loads. However, the exact improvement will vary depending on driving habits and other modifications.
- Enhanced Sound: One of the most attractive features for many owners is the improved sound. A 5-inch system typically produces a deeper, more aggressive exhaust note, enhancing the overall driving experience. The specific sound will depend on the chosen exhaust brand and muffler type.
- Lower EGTs (Exhaust Gas Temperatures): Reducing exhaust gas temperatures is crucial for engine longevity and preventing damage. A larger diameter exhaust system helps dissipate heat more efficiently.
What's the Difference Between a 4-Inch and a 5-Inch Exhaust?
While both 4-inch and 5-inch exhaust systems offer performance benefits, the 5-inch system provides a more significant improvement, particularly at higher horsepower levels. The larger diameter of the 5-inch system allows for even greater exhaust flow, minimizing backpressure and maximizing power gains. The difference may be subtle at lower power outputs, but becomes increasingly apparent with modifications that significantly increase engine power.
Does a 5-Inch Turbo-Back Exhaust Void My Warranty?
Modifying your vehicle's exhaust system can potentially void your warranty, especially if the modification causes damage to the engine or other components. It's crucial to check your warranty terms and conditions carefully. Additionally, installing a high-quality exhaust system from a reputable manufacturer can help mitigate the risk. It's always advisable to consult with your dealership before making any modifications.
How Much Does a 5-Inch Turbo-Back Exhaust Cost?
The cost of a 5-inch turbo-back exhaust system for a 6.7 Power Stroke varies depending on the brand, materials used (stainless steel is typically more expensive than aluminized steel), and features included. You can expect to pay anywhere from a few hundred dollars to several thousand dollars, depending on the system's complexity and components.
What are the Best Brands for 5-Inch Turbo-Back Exhausts?
Several reputable manufacturers produce high-quality 5-inch turbo-back exhaust systems for the 6.7 Power Stroke. Researching different brands and reading customer reviews is crucial to finding the best option for your needs and budget. Consider factors such as materials, craftsmanship, warranty, and sound profile when making your decision. Popular brands often include names like Flo-Pro, MBRP, and others.

Will a 5-Inch Exhaust Increase Fuel Mileage?
While a 5-inch exhaust system can contribute to improved fuel economy by reducing backpressure, the overall improvement might be modest. The extent of the increase will largely depend on your driving style and other modifications to the vehicle. Focusing primarily on fuel economy improvements should involve a more holistic approach beyond just exhaust modifications.
This guide provides a comprehensive overview of 5-inch turbo-back exhaust systems for the 6.7 Power Stroke. Remember to always research thoroughly and consider all factors before making a purchase. Consult with a qualified mechanic if you have any doubts or concerns about the installation process.
