Improve the power and performance of your 2011–14 Ford F-150 5.0L with premium long tube headers from Stainless Works. Choose your connection with either a true dual setup with our catback or go with the factory connection to the stock exhaust or another aftermarket system.
Starting with 3/8" thick flanges welded to 1-3/4" or 1-7/8" primaries, these headers flow into slip-fit collectors with an integrated merge spike. Finally they finish into our high-flow catalytic converters for maximum performance and emissions compliance.
Built from corrosion-resistant 304 stainless steel and fully TIG welded for strength and durability at our state-of-the-art facility in Streetsboro, Ohio — engineered for long-term performance.
