The factory manifold was formed with a pinch\/crease for steering column clearance that restricts three of the four cylinders on the driver side to 80% flow, causing exhaust pressure imbalance and higher EGTs. This no-pinch design removes that restriction to restore flow, supporting better turbo response and overall exhaust efficiency for daily driving, towing, hauling, and performance-focused builds.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001–2008 Chevrolet Silverado and GMC Sierra 2500\/3500 with 6.6L Duramax diesel (direct bolt-on)\u003c\/li\u003e\n  \u003cli\u003e2009–2015 Chevrolet Silverado and GMC Sierra 2500\/3500 with 6.6L Duramax diesel (factory replacement)\u003c\/li\u003e\n  \u003cli\u003eCompatible with LB7, LLY, LBZ, LMM, and LML engine codes\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 High-quality ductile silica moly cast iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 10.8 lbs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 9.0\" W × 4.0\" H × 25.0\" L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Hardware:\u003c\/strong\u003e Exhaust manifold gasket, exhaust outlet gasket, and three Y-pipe bolts with washers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance Benefits:\u003c\/strong\u003e Flows better than the original driver-side manifold with less restriction to match passenger-side manifold flow\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThis is a direct bolt-on upgrade for 2001–2008 trucks; consult with a qualified mechanic before attempting installation.
