Description
Unlock more low-end torque and improve throttle response in your 2011–2014 Ford F-150 5.0L with the Stainless Works 1-3/4" Long Tube Headers with High-Flow Cats and Y-Pipe (Factory Connect). Designed for those who prioritize torque and mid-range performance, this complete header system delivers a refined balance of power, sound, and seamless compatibility with your stock exhaust.
These headers are crafted from premium 304L stainless steel and feature 1-3/4" mandrel-bent primaries, ideal for maximizing torque in naturally aspirated applications. The 3/8" thick CNC laser-cut flanges ensure a strong, secure seal at the head, while slip-fit collectors with integrated merge spikes enhance exhaust scavenging and flow efficiency.
Engineered for factory connection, this kit includes a 3" Y-pipe that mates directly to your OEM cat-back exhaust or compatible aftermarket systems, making it a plug-and-play upgrade that boosts performance without requiring a full exhaust replacement.
The system is finished with high-flow catalytic converters, allowing for improved exhaust flow and reduced backpressure without sacrificing emissions compliance. Each component is TIG welded for precision and durability, and like all Stainless Works products, it is proudly made in the USA and backed by a lifetime warranty on materials and craftsmanship.
