The original thin-wall rubber hoses harden, swell, and split along flex seams, while OEM worm-gear clamps lose clamping force under heat. This degradation causes severe boost loss, elevated exhaust gas temperatures (EGTs), excessive soot output, and turbocharger overspeeding under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit upgrades the entire boost tract using mandrel-bent 3-inch aluminum piping finished with an electrophoresis coating to resist underhood heat and corrosion. The mandrel-bent profile eliminates factory airflow restrictions for steady pressure velocity. Heavy-duty multi-ply silicone boots provide superior resistance to oil saturation and thermal fatigue, secured by constant-tension stainless steel T-bolt clamps to eliminate blow-offs at both stock and elevated boost levels.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Mandrel-Bent Hot-Side Intercooler Pipe (3-Inch)\u003c\/li\u003e\n  \u003cli\u003e1x Mandrel-Bent Cold-Side Intercooler Pipe (3-Inch)\u003c\/li\u003e\n  \u003cli\u003e2x Multi-Ply Silicone Transition Boots (2.30\" to 3.00\")\u003c\/li\u003e\n  \u003cli\u003e2x Multi-Ply Straight Silicone Boots (3.00\")\u003c\/li\u003e\n  \u003cli\u003e3x 2.75-Inch Stainless Steel T-Bolt Clamps\u003c\/li\u003e\n  \u003cli\u003e6x 3.25-Inch Stainless Steel T-Bolt Clamps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2002-2004 GMC Sierra\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e6.6L LB7 Duramax \/ GMT800\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e300 hp \/ 520 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2004 GMC Sierra 2500 HD (6.6L V8 LB7 Duramax Turbo Diesel)\u003c\/li\u003e\n  \u003cli\u003e2002-2004 GMC Sierra 3500 (6.6L V8 LB7 Duramax Turbo Diesel)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT800 Sierra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2004 GMC Sierra equipped with the \u003cstrong\u003e6.6L LB7 Duramax\u003c\/strong\u003e engine. \u003cstrong\u003eDoes not fit 2004.5-2005 LLY Duramax models.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWill this kit hold up on tuned applications?\u003c\/h4\u003e\n\u003cp\u003eYes, the 3-inch rigid aluminum tubing and high-strength multi-ply silicone boots with T-bolt clamps are engineered to reliably handle higher manifold pressures than stock.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned specifically to handle severe-duty hauling and towing demands, this charge pipe system restores boost integrity, safeguards turbocharger efficiency, and ensures long-term operational durability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67612009169144,"sku":"DS-E7TWAWO8F","price":124.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/intercooler-pipe-boot-kit-for-gmc-sierra-2002-2004-6-6l-duramax-lb7-1.jpg?v=1791592189","url":"https:\/\/performancechiptuning.com\/fr\/products\/intercooler-pipe-boot-kit-for-gmc-sierra-2002-2004-6-6l-duramax-lb7","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
