{"product_id":"1-5-8-shorty-tuned-length-exhaust-header","title":"1-5\/8\" Shorty Tuned-Length Exhaust Header","description":"The BBK Performance 3516 is a shorty tuned-length exhaust header engineered to increase exhaust flow and performance for 1997-1998 Ford F-150 and Expedition 5.4L trucks. These headers replace restrictive factory manifolds with heavy-gauge 1-5\/8 inch tubing and large-bore collectors to optimize engine efficiency.\n\nConstructed with 3\/8-inch laser-cut one-piece flanges and CNC mandrel-bent tubing, the assembly is finished in a durable nickel chrome coating. Each kit includes the necessary gaskets and hardware for a direct-fit replacement, and the system is 50-state EPA legal.\n\nTo ensure long-term performance and prevent exhaust leaks after installation, BBK recommends that you re-torque the header bolts after the initial heat cycle. While these headers are designed as a direct fit for the specified 1997-1998 5.4L applications, proper clearance and installation should be verified during the mounting process.","brand":"BBK 1-5\/8","offers":[{"title":"Default Title","offer_id":52664193483064,"sku":"3516","price":399.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/684796501.jpg?v=1784334982","url":"https:\/\/store.motormia.co\/products\/1-5-8-shorty-tuned-length-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
