These high-performance headers improve exhaust flow, resulting in noticeable gains in horsepower and torque. Whether you're looking for better acceleration, a more aggressive engine sound, or improved fuel efficiency, 5.4 Triton headers are designed to deliver these benefits and more. \u003c\/span\u003e\n\u003c\/h2\u003e\n\u003ch2\u003e\u003cspan\u003e\u003cmeta charset=\"utf-8\"\u003eOutlet Size: 2.25\" Primary Tube Size: 1.75\" Head Flange Thickness: 7\/16 inch Outlet Flange Thickness: 3\/8 inch Additional Info: 5.4L Models Only CNC machine flanges with TIG and MIG welded construction.

While reliable, they restrict exhaust flow and limit the engine’s full potential. Upgrading to performance headers is one of the most effective ways to improve power, efficiency, and driving response. Horsepower \u0026amp; Torque Gains: Up to 8–20 HP and 11 lb-ft of torque for more responsive driving Reduced back pressure: Stock manifolds restrict exhaust flow, limiting horsepower and throttle response Improved exhaust scavenging: Headers allow exhaust gases to exit each cylinder more efficiently Better engine efficiency: Smoother exhaust flow helps the engine perform more effectively under load and acceleration Enhanced exhaust sound: Produces a deeper, more aggressive tone compared to factory manifolds For Ford F-150 owners with the 5.4L Triton V8, headers are more than a sound upgrade—they deliver real, functional performance improvements you can feel every time you drive. \u003c\/span\u003e\u003cspan style=\"color: rgb(0, 0, 0);\"\u003e\u003cspan\u003e\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/h2\u003e","brand":"Predator Performance®","offers":[{"title":"Default Title","offer_id":42314812555358,"sku":"PP-FLES08261","price":151.19,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0030\/5315\/8515\/files\/Screenshot_2026-04-08_at_3.10.36_PM.png?v=1775686330","url":"https:\/\/10secondracing.com\/en-gb\/products\/04-14-ford-f-150-5-4l-304ss-short-tube-exhaust-headers","provider":"10 Second Racing","version":"1.0","type":"link"}
