These manifolds and up-pipes are designed to lower EGT's, reduce drive pressure and accelerate turbo spool-up time. The up-pipes feature heavy duty bellows that are internally sleeved and are manufactured from aircraft grade material, improving exhaust flow to the turbocharger and reducing restriction in your LB7 Duramax performance build.\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001–2004 Chevrolet Silverado 2500HD\/3500HD — LB7\u003c\/li\u003e\n  \u003cli\u003e2001–2004 GMC Sierra 2500HD\/3500HD — LB7\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp Pipe Construction:\u003c\/strong\u003e Aircraft-grade 304 stainless steel with .120\" wall thickness and internally sleeved bellows\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Improvement:\u003c\/strong\u003e Up to 55% increase in air flow over stock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManifold Material:\u003c\/strong\u003e High quality Silica Moly Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInternal Design:\u003c\/strong\u003e Designed with a gradual increase in internal diameter as more exhaust ports are added, allowing for added volume within the manifold while keeping the maximum velocity possible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance Benefits:\u003c\/strong\u003e Designed to lower EGT's, reduce drive pressure and accelerate turbo spool-up time— all while maintaining reliability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions:\u003c\/strong\u003e Kit includes exhaust manifold gaskets, up-pipe to turbo gaskets, up-pipe to manifold gaskets, and bolts — all gaskets necessary to install these high-flow manifolds and up-pipes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDownpipe Compatibility:\u003c\/strong\u003e Factory downpipe (2001-2004 LB7 only) does not fit aftermarket manifolds and up-pipes\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eThese up pipes are a direct bolt-on replacement for factory-style components when paired with a compatible cast race manifold.
