This factory configuration creates unnecessary backpressure downstream of the mid-pipe and adds excessive dead weight behind the rear axle. Furthermore, the mild-grade factory steel construction is vulnerable to environmental corrosion, road salt deterioration, and heat cycle degradation over extended service intervals.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis axle-back setup delivers a straight-through flow design fabricated from corrosion-resistant \u003cstrong\u003e304 stainless steel\u003c\/strong\u003e tubing. By eliminating the factory baffled chambers, exhaust gas velocity is preserved across the exit path, reducing turbulence at the tail section. Precision mandrel bends ensure continuous diameter integrity without restrictive crimps, while heavy-duty TIG-welded hanger brackets align directly with the factory rubber exhaust isolators. The system integrates polished dual-wall exhaust tips that fill the bumper valance cutouts accurately without heat clearance issues.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePair of 304 stainless steel axle-back exhaust pipes with pre-welded tips\u003c\/li\u003e\n  \u003cli\u003eMounting hardware kit (flange bolts and 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: solid font-size: min-width:\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;\"\u003e2022-2026 Subaru WRX\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;\"\u003eFA24DIT (2.4L Turbo) \/ VB\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;\"\u003e271 hp \/ 258 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-MD119-BT\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\u003e2022 Subaru WRX 2.4L Turbo (Base, Premium, Limited, GT)\u003c\/li\u003e\n  \u003cli\u003e2023 Subaru WRX 2.4L Turbo (Base, Premium, Limited, GT)\u003c\/li\u003e\n  \u003cli\u003e2024 Subaru WRX 2.4L Turbo (Base, Premium, Limited, GT, TR)\u003c\/li\u003e\n  \u003cli\u003e2025 Subaru WRX 2.4L Turbo (All trims)\u003c\/li\u003e\n  \u003cli\u003e2026 Subaru WRX 2.4L Turbo (All trims)\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 VB WRX?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2022-2026 Subaru WRX equipped with the \u003cstrong\u003eFA24DIT\u003c\/strong\u003e 2.4L turbo engine; it will not fit previous generation VA chassis models or naturally aspirated Subaru platforms.\u003c\/p\u003e\n\n\u003ch4\u003eAre aftermarket ECU recalibrations required after installing this axle-back?\u003c\/h4\u003e\n\u003cp\u003eNo, because this system mounts downstream of the catalytic converters and primary oxygen sensors, it operates safely without triggering a Check Engine Light or requiring ECU tuning.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle high-rpm exhaust pulses and harsh driving environments, this direct-fit stainless steel assembly delivers an uninhibited boxer exhaust note while maintaining reliable mechanical tolerances on your modern turbocharged platform.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68046611677432,"sku":"DS-EJGR0ZIA7","price":363.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/axle-back-exhaust-for-subaru-wrx-2022-2026-2-4l-1.jpg?v=1794266658","url":"https:\/\/performancechiptuning.com\/fr\/products\/axle-back-exhaust-for-subaru-wrx-2022-2026-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
