{"product_id":"3-5-inch-high-flow-turbo-downpipe-exhaust","title":"3.5-Inch High-Flow Turbo Downpipe Exhaust","description":"The Spelab 3.5-Inch High-Flow Turbo Downpipe Exhaust is engineered to optimize performance by replacing the restrictive factory downpipe on turbocharged vehicles. Its large 3.5-inch diameter design promotes dramatically increased exhaust flow, which helps reduce turbo lag and enhance throttle response. This improved flow minimizes backpressure, allowing the turbocharger to spin faster, produce more boost, and ultimately generate more power.\n\nIt directly replaces the OEM unit, addressing the performance bottleneck created by the factory downpipe and providing a solid foundation for further performance modifications such as tuning and increased boost levels.\n\nThis downpipe is specifically designed for 2017-2025 Chevrolet Silverado \u0026amp; GMC Sierra 2500 \u0026amp; 3500HD models equipped with the 6.6L Duramax engine. It will not fit Cab \u0026amp; Chassis trucks. Installation may require removing the turbo. Review customer feedback for installation tips, such as wearing gloves when handling heat wrap.","brand":"Spelab","offers":[{"title":"Default Title","offer_id":52871960822072,"sku":"SPES08074-IS08196S","price":228.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/3-5-inch-high-flow-turbo-downpipe-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
