{"product_id":"v8-exhaust-header","title":"V8 Exhaust Header","description":"Upgrade your vehicle’s performance with the Flashark Exhaust Header, specifically designed for 1999-2006 Chevy Avalanche, Suburban, Tahoe, GMC Sierra, and Yukon GMT800 models equipped with 4.8L, 5.3L, and 6.0L V8 engines. This header improves airflow and reduces back pressure by giving each cylinder its own exhaust pipe, which prevents interference and increases horsepower and engine efficiency.\n\nConstructed from durable 201 stainless steel with a mirror-polish finish, this performance exhaust component is built to last. The primary tubes measure 1.875\" and the main piping diameter is 2.5\", with an outlet size of 2.5\". It also features a port for the EGR valve, ensuring compatibility with emissions systems on certain models.\n\nInstallation is designed as a direct bolt-on to the cylinder heads. However, due to the long tube design, connecting to your existing exhaust system will require a matching Y-pipe or custom work at a muffler shop. For optimal performance, a PCM tune is highly recommended to maximize the benefits of the increased airflow and prevent potential check engine lights.\n\nThis header is engineered to clear the front driveshaft and differential on 4WD models, ensuring fitment for both 2WD and 4WD configurations. It is compatible with a wide range of GMT800 platform vehicles from 1999-2006, including the Silverado 1500, Sierra 1500, Avalanche 1500, Tahoe, and Yukon, provided they are equipped with the 4.8L, 5.3L, or 6.0L V8 engines.","brand":"Flashark","offers":[{"title":"Default Title","offer_id":52688372826424,"sku":"FLES08203","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663686049.webp?v=1784889274","url":"https:\/\/store.motormia.co\/products\/v8-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
