If you’re using a cold air intake, cat-back exhaust, or tuner on your 2011–2014 Mustang 3.7L, these 1-7/8” shorty headers from Flowtech are the upgrade you need to take your ride to the next level.
Providing a terrific combination of quality and value, these headers offer consistent tubing diameters, smooth flow, and increased exhaust velocity thanks to mandrel-bent 409 stainless steel (or 304 SS) set in heavy-duty, 16-gauge tubing. In addition, the 1-7/8” diameter primary tubes offer improved throttle response. Premium aluminum gasket headers are included, and three finishes are available: Natural (12140FLT; 409 SS), Polished (12141FLT; 304 SS), and Silver Ceramic (32141FLT; 409 SS).
