These internal neck-downs bottleneck exhaust velocity directly downstream of the catalytic converter, causing parasitic pumping losses and trapping thermal energy. Under heavy trail crawl or sustained mountain inclines, the stock setup restricts the \u003cstrong\u003e1GR-FE\u003c\/strong\u003e and \u003cstrong\u003e2TR-FE\u003c\/strong\u003e powerplants from venting combusted gases cleanly.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eConstructed from mandrel-bent \u003cstrong\u003e304 stainless steel\u003c\/strong\u003e, this cat-back system maintains smooth, constant-diameter tubing walls to maximize volumetric scavenging and eliminate flow separation. The straight-through design reduces backpressure against the exhaust valves while standing up to high thermal cycles and chemical corrosion. Heavy-gauge factory-style mounting brackets, high-integrity weld joints, and matched mating flanges provide a robust, leak-free connection designed for rigorous off-camber articulation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCat-back exhaust piping\u003c\/li\u003e\n  \u003cli\u003eExhaust tip section\u003c\/li\u003e\n  \u003cli\u003eMounting hardware\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;\"\u003e2010-2024 Toyota 4Runner\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;\"\u003e1GR-FE (4.0L), 2TR-FE (2.7L) \/ N280\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;\"\u003e157-270 hp \/ 178-278 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;\"\u003eB-EXT-CB062, 2010, 2011, 2012, 2013, 2014, 2015\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\u003e2010 Toyota 4Runner 2.7L\u003c\/li\u003e\n  \u003cli\u003e2010-2024 Toyota 4Runner 4.0L\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 N280 4Runner?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2010-2024 Toyota 4Runner equipped with the \u003cstrong\u003e1GR-FE\u003c\/strong\u003e (4.0L) or 2010 \u003cstrong\u003e2TR-FE\u003c\/strong\u003e (2.7L) engine. \u003cstrong\u003eIt does not fit non-listed model years or engine configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre mounting hardware and tips included?\u003c\/h4\u003e\n\u003cp\u003eYes, this system includes the pictured tip section and mounting hardware necessary to bolt directly to the catalytic converter outlet flange.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Off-Road Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe trail conditions and overland hauling, this system delivers uncompromising thermal resistance, clearance, and structural durability without cracking at the joints under chassis flex.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68046661026040,"sku":"DS-E3AXTMCSU","price":428.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/cat-back-exhaust-for-toyota-4runner-2010-2024-2-7l-4-0l-1.jpg?v=1794267992","url":"https:\/\/performancechiptuning.com\/fr\/products\/cat-back-exhaust-for-toyota-4runner-2010-2024-2-7l-4-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
