The factory exhaust manifolds on your 5.0L Coyote F-150 are leaving power on the table. Speed Engineering's 1-7/8" longtube headers are a direct-fit, dyno-proven upgrade that frees up exhaust flow, improves throttle response, and delivers over 25 rear-wheel horsepower gained over stock — built from 304 natural stainless steel and engineered to fit right the first time.
Every set is mandrel bent, TIG-welded, and built with CNC-machined flanges for a precise, leak-free fit at the cylinder head and collector.
Features:
- 1-7/8" Port-Matched Primary Tubes — Full-diameter flow from cylinder head to collector for maximum exhaust scavenging
- 3" Collector — Optimized for strong low-to-mid RPM torque
- Mandrel Bent Tubing — Consistent tube diameter through every bend; no crimping, no restriction
- CNC Machined Flanges — Precision fit at the head and collector for a leak-free seal
- 304 Natural Stainless Steel Construction — Corrosion resistant, heat tolerant, and built to last
- Longtube Header Design — Maximum scavenging efficiency vs. shorty or mid-length headers
- Standard Graphite Manifold Gaskets Included
- Dyno Proven — 25+ RWHP gain on 5.0L Coyote applications
- V8 Only — Compatible with 5.0L Coyote engines only
Important Installation Note — Header Bolt Thread Pitch:
Header bolt thread pitch varies by Coyote generation — verify before installation:
- Early Gen 1 (2011) and some Gen 3 (2018+): M10x1.25
- Late Gen 1 (2011) and Gen 2 (2015–2017): M10x1.5
Optional: Zinc Coated Header Bolts (M10x1.5) can be added at the time of purchase.

FAQ
How much horsepower do these headers add to a 5.0L Coyote F-150?
Speed Engineering's 1-7/8" longtube headers are dyno proven to add over 25 rear-wheel horsepower on 5.0L Coyote F-150 applications compared to stock exhaust manifolds.
Do these fit both 2WD and 4WD F-150 trucks?
Yes. These headers are compatible with both 2WD and 4WD configurations on all listed 2011–2025 Ford F-150 5.0L Coyote applications.
What header bolt size do I need for my F-150?
It depends on your Coyote generation. Early Gen 1 (2011) and some Gen 3 (2018+) engines use M10x1.25 bolts. Late Gen 1 (2011) and Gen 2 (2015–2017) engines use M10x1.5 bolts. Verify your thread pitch before installation. Optional zinc coated header bolts in M10x1.5 are available at the time of purchase.
What gaskets are included?
Standard graphite manifold gaskets are included with the headers.
What material are these headers made from?
304 natural stainless steel with full TIG-welded construction and CNC-machined flanges for a precise, durable, leak-free fit.
Are these headers street legal?
No. These are race-only headers intended for closed-course competition use only. Installation on a street-driven vehicle may violate the Clean Air Act (42 U.S.C. 7522(a)(3)).
