aFe Twisted Steel Shorty Header 11-17 Ford Mustang V6-3.7L

The aFe Twisted Steel Shorty Header for the 2011–2017 Ford Mustang V6 3.7L is a high-performance exhaust component designed to boost engine output and efficiency. Constructed from 1-5/8 inch mandrel-bent 409 stainless steel tubing, this header ensures maximum strength and long-lasting durability. It features factory-style laser-cut machined mild steel flanges for a secure, leak-free seal. The 3-to-1 mitered merge collectors reduce exhaust turbulence and increase velocity, resulting in gains of up to 14 horsepower and 15 lb-ft of torque, as verified on aFe’s in-house dynamometer. This header improves throttle response and overall engine performance while maintaining a robust build quality suitable for demanding driving conditions.

This shorty header is designed specifically for the 2011 to 2017 Ford Mustang equipped with the 3.7L V6 engine. It serves as a direct replacement for the factory exhaust manifold, providing a bolt-on installation with included gaskets and hardware for a straightforward upgrade. Ideal for street and performance driving, this header enhances exhaust flow without requiring extensive modifications. Its compatibility with the stock exhaust system makes it suitable for daily driving and occasional spirited use, delivering noticeable improvements in power and responsiveness while maintaining reliability and ease of installation.
