{"product_id":"3-inch-stainless-steel-downpipe-exhaust","title":"3-Inch Stainless Steel Downpipe Exhaust","description":"The Flashark 3-Inch Downpipe Exhaust is engineered for 2004.5-2010 Chevrolet Silverado 2500HD\/3500HD and GMC Sierra 2500HD\/3500HD models equipped with the 6.6L Duramax LLY, LBZ, or LMM diesel engines.\n\nUpgrading from the stock downpipe can significantly improve your Duramax's performance by reducing factory restrictions. This enhanced exhaust flow allows the turbo to spool faster, leading to quicker response times, especially at lower RPMs. The improved airflow can contribute to modest gains, typically estimated between 5-15 hp and 10-25 lb-ft of torque, depending on the specific truck's setup. Additionally, the improved flow helps create a deeper, more engaging diesel tone without excessive noise.\n\nInstallation can be completed by owners with basic mechanical knowledge, though professional installation is recommended for optimal fitment. It includes the necessary clamps, hardware, and gaskets for a complete installation.\n\nIt is important to note that this downpipe is not compatible with Cab \u0026amp; Chassis truck models. Furthermore, performance downpipes can impact emissions compliance, and this specific Flashark downpipe is not CARB-approved for use in California.","brand":"Flashark","offers":[{"title":"Default Title","offer_id":52688372433208,"sku":"FLES08045","price":119.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663174022.webp?v=1784889269","url":"https:\/\/store.motormia.co\/products\/3-inch-stainless-steel-downpipe-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
