Over time, moisture accumulation rots out the internal muffler baffles and seam welds, leading to structural fatigue at the hanger junctions. This deterioration causes excessive cabin drone, dangerous exhaust gas leakage under the passenger floorboards, and backpressure anomalies that can trigger oxygen sensor trouble codes along the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered as a complete bolt-on solution for the 4.7L \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e V8, this replacement assembly is manufactured from heavy-duty 409 stainless steel to withstand road debris abrasion, thermal shock, and surface oxidation. Consistent cross-sectional tubing geometry is maintained through smooth mandrel bends, preventing the scavenging bottlenecks common to standard crush-bent pipes. Factory-style laser-cut flanges and welded, heavy-gauge steel hanger rods match factory mounting bushings directly, ensuring precise chassis alignment and leak-free sealing without the need for custom fabrication, cutting, or welding.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1 Exhaust System assembly (muffler and intermediate tailpipe section)\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;\"\u003e2005-2006 Toyota Tundra\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;\"\u003e2UZ-FE \/ XK30, XK40\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;\"\u003e282 hp \/ 325 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\u003e2005-2006 Toyota Tundra 4.7L V8 Double Cab \/ Crew Cab\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 XK30\/XK40 Tundra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2005-2006 Toyota Tundra equipped with the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e engine. \u003cstrong\u003eThis unit fits Double Cab and Crew Cab configurations only; it does NOT fit Regular Cab or Access Cab models.
