Harrop Stage 2 | 395KW

Mustang GT Stage 2 | 395KW

The Mustang 5.0L Stage 2 upgrade is designed to take your vehicle's performance to the next level through a series of key enhancements. The upgrade process begins with our trained technician fitting a high-flow cold air intake system, which significantly improves the engine's breathing capabilities and delivers a more aggressive sound.

Next, we install a set of 1 7/8" 4-into-1 headers equipped with high-flow metallic catalytic converters. This upgrade not only further enhances exhaust flow but also reduces back pressure, allowing the engine to perform more efficiently. To complete the exhaust modifications, we fit a 3-inch stainless steel cat-back exhaust system, which ensures optimal exhaust flow while providing an exhilarating sound.

Once all the components are installed, we conduct a custom tune of your vehicle's ECU on the dynamometer. Utilizing the latest Ford ECU tuning software, we optimize the engine for maximum power, torque, and fuel efficiency, ensuring that all upgrades work together seamlessly.

The upgrade process concludes with thorough road testing, enabling us to make any necessary final adjustments to further enhance your vehicle's performance and drivability. At the end of the upgrade, we provide you with a dyno graph that compares the power and torque figures before and after the HPF upgrade, clearly demonstrating the significant improvements achieved.

Like all HPF upgrade packages, the Stage 2 upgrade is modular, allowing customers to add further enhancements in the future without incurring unnecessary costs. HPF is dedicated to delivering maximum performance through high-quality components while maintaining a strong focus on reliability and drivability throughout the upgrade process.
