Built for heavy-duty diesel use, this manifold is a reliable upgrade for replacing cracked, leaking, warped, or restrictive factory-style components and is suitable for daily driving, towing, hauling, and performance-focused Duramax applications.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017–2019 Chevrolet Silverado 2500\/3500 HD -- 6.6L Duramax L5P\u003c\/li\u003e\n  \u003cli\u003e2017–2019 GMC Sierra 2500\/3500 HD -- 6.6L Duramax L5P\u003c\/li\u003e\n  \u003cli\u003e2020–2025 Chevrolet Silverado 2500\/3500 HD -- 6.6L Duramax L5P\u003c\/li\u003e\n  \u003cli\u003e2020–2025 GMC Sierra 2500\/3500 HD -- 6.6L Duramax L5P\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast high-sil moly construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp-Pipe Construction:\u003c\/strong\u003e Aircraft-grade 304 stainless steel bellows with internally sleeved design and increased inner diameter for higher flow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp-Pipe Wall Thickness:\u003c\/strong\u003e .120-inch wall thickness with 2-inch outside diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance Benefits:\u003c\/strong\u003e Lowers exhaust gas temperatures (EGTs), accelerates turbo spool-up, and increases power and fuel economy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEGT Port:\u003c\/strong\u003e Pre-molded and tapped for EGT gauge sensor installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware:\u003c\/strong\u003e Includes 16 exhaust manifold mounting bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThis is a direct-fit replacement for factory manifolds on 2017–2025 models.
