{"product_id":"1-3-4-long-tube-exhaust-headers","title":"1-3\/4\" Long Tube Exhaust Headers","description":"The BBK Performance 1633 long tube exhaust headers are engineered to significantly boost horsepower and torque in your 2011-2023 Ford Mustang GT or Boss 302. Featuring 1-3\/4\" CNC-machined mandrel-bent primaries, these headers are designed for unrestricted exhaust flow, contributing to a typical 30+ horsepower increase.\n\nConstructed from 16-gauge steel tubing with 3\/8\" thick exhaust header flanges to resist heat distortion, the headers are finished in a durable titanium ceramic coating. The design includes a leak-free ball \u0026amp; socket collector and is compatible with both manual and automatic transmissions. Gaskets and hardware are included for installation, though OE header studs may need to be reused. A BBK Performance mid-pipe is required for installation.\n\nInstallation requires specific steps including disconnecting the battery, removing various engine components for access, and re-installing the starter and motor mounts. The oxygen sensors will need to be transferred to the provided bungs, and it's recommended to use anti-seize on the threads. For proper functionality, front O2 wire harness extensions are necessary and must be purchased separately based on the Coyote engine generation (GEN1: 11-14, GEN2: 15-17, GEN3: 18-23). Failure to check the correct thread pitch for the included header bolts can result in cylinder head damage.\n\nThese headers are not C.A.R.B. approved and cannot be installed on emission-controlled vehicles in California, nor can they be sold or shipped to California residents. BBK Performance provides a 1-year factory warranty on their parts.","brand":"BBK Performance","offers":[{"title":"Default Title","offer_id":52687076327736,"sku":"BBK 1633","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660185938.jpg?v=1784880105","url":"https:\/\/store.motormia.co\/products\/1-3-4-long-tube-exhaust-headers","provider":"MOTORMIA","version":"1.0","type":"link"}
