{"product_id":"201-stainless-steel-exhaust-header","title":"201 Stainless Steel Exhaust Header","description":"The Flashark Exhaust Header is engineered to enhance the performance of 1999-2006 Chevrolet Avalanche, Suburban, Tahoe, GMC Sierra, and Yukon GMT800 models equipped with 4.8L, 5.3L, or 6.0L V8 engines.\n\nBy providing each cylinder with an independent exhaust pipe, these long tube headers significantly improve exhaust scavenging compared to restrictive factory manifolds. This design minimizes back pressure, allowing the engine to breathe more freely, particularly in the mid-to-high RPM range, which results in noticeable gains in horsepower and torque. For optimal performance, a professional PCM tune is highly recommended to calibrate for the increased airflow and prevent potential check engine lights.\n\nHowever, due to their extended length, connection to the existing exhaust system will require a matching Y-pipe or custom work at a muffler shop. The kit includes necessary manifold port gaskets and hardware, with anti-seize recommended for bolts during installation. This header is designed to accommodate vehicles with an EGR valve, ensuring emissions compliance for earlier GMT800 models.\n\nThese headers are engineered to provide clearance for the front driveshaft and differential on 4WD models, ensuring fitment for both 2WD and 4WD configurations. The product fits 1999-2006 Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Avalanche 1500, and 1999-2006 Chevrolet Tahoe and GMC Yukon models with the specified V8 engines.","brand":"5.3L","offers":[{"title":"Default Title","offer_id":52686710669624,"sku":"FLES08203","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660670762.webp?v=1784876120","url":"https:\/\/store.motormia.co\/products\/201-stainless-steel-exhaust-header","provider":"MOTORMIA","version":"1.0","type":"link"}
