{"product_id":"long-tube-header-for-gm-vortec-v8","title":"Long Tube Header for GM Vortec V8","description":"The Flashark long tube header kit provides a foundation for improved exhaust flow on compatible GM Vortec V8 vehicles, aiming to deliver a deeper V8 tone and potentially sharper throttle response. Constructed from 201 stainless steel with a mirror-polished finish, these headers are built for both performance and durability.\n\nThe kit offers two primary options: 'Long Tube Only' for custom exhaust setups, and 'Long Tube with Y-Pipe' for a more integrated upgrade path. Specifications vary between these options, including primary tube diameter (1.75\" for Long Tube Only, 1.7\" for Long Tube with Y-Pipe) and outlet size (3.00\" vs. 2.4\"). Both feature 7\/16\" head flange thickness and 3\/8\" outlet flange thickness, and include standard factory O2 sensor locations, with the Y-pipe option adding a third O2 sensor port.\n\nFitment is critical and restricted to 2007-2014 GM full-size 2WD (RWD) models equipped with 4.8L, 5.3L, 6.0L, or 6.2L Vortec gasoline V8 engines. It is explicitly not compatible with any 4WD\/4x4 variants. Buyers must confirm their vehicle's drivetrain and engine specifications. A specific warning is issued for the 2014 Silverado 1500 5.3L EcoTec3, which this product does not fit. It also will not fit diesel engines or vehicles not listed in the detailed Fitment \u0026amp; Compatibility table. Professional installation is recommended due to potential complexities such as rusted bolts, tight clearances, and exhaust modifications.\n\nWhile long tube headers can support performance gains, actual results vary based on numerous factors including engine condition, supporting exhaust components, and the presence of a proper tune. Buyers are responsible for verifying local emissions and noise regulations.","brand":"Flashark","offers":[{"title":"Default Title","offer_id":52688309354808,"sku":"EH28969\u0026EH28932(ES08205)","price":309.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663685730.webp?v=1784889143","url":"https:\/\/store.motormia.co\/products\/long-tube-header-for-gm-vortec-v8","provider":"MOTORMIA","version":"1.0","type":"link"}
