By removing the catalytic converter and DPF assembly, this Duramax L5P delete pipe allows exhaust gases to exit the turbocharger with significantly less restriction. The result is improved exhaust flow, reduced backpressure, and a cleaner path for performance-oriented tuning applications.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eYears:\u003c\/strong\u003e 2017–2026\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMakes:\u003c\/strong\u003e Chevrolet, GMC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModels:\u003c\/strong\u003e Silverado 2500HD, Silverado 3500HD, Sierra 2500HD, Sierra 3500HD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e 6.6L Duramax L5P Diesel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImportant:\u003c\/strong\u003e Fits pickup trucks only. \u003cstrong\u003eDoes not fit 3500\/4500\/5500 Cab \u0026amp; Chassis models\u003c\/strong\u003e.
