How Much HORSEPOWER Do Headers Pick Up? (Wengerd Performance Dyno Tuning)

In this video we upgrade the Mustang with Stainless Power headers and compare them directly to the factory stock headers. If you’ve ever wondered whether headers are actually worth it, this install and side-by-side comparison will show you the difference in sound, airflow, and performance. Then, we compare the factory Whipple tune from factory with Wengerd Performance's 93 octane tune. We show the power differences and torque differences and how power carries out through the dyno pulls themselves. 🔥 What we cover in this video: Removing the factory Mustang headers Installing Stainless Power headers Differences in design vs. stock headers Tuning comparisons Performance and throttle response improvements Why Stainless Power headers are better than OEM The upgraded headers improve exhaust scavenging, which can lead to better horsepower, improved throttle response, and a more aggressive exhaust tone. Stainless steel also offers better durability and resistance to rust compared to the factory components. If you’re planning Mustang performance mods, headers are one of the most noticeable upgrades you can make — especially when paired with a proper tune and exhaust setup. 👍 If you enjoyed the video: Like the video Subscribe for more Mustang builds, installs, and performance comparisons Drop a comment if you’ve upgraded your headers or are thinking about it! #Mustang #CarMods #PerformanceHeaders #MustangBuild #ExhaustUpgrade
