These factory mufflers generate turbulent backpressure directly after the mid-pipe split and add substantial unsprung chassis weight at the extreme rear overhang. Furthermore, the mild factory steel construction is susceptible to road salt corrosion, surface rust, and fatigue around the hanger welds over extended drive cycles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis axle-back muffler delete system utilizes smooth, mandrel-bent \u003cstrong\u003eT304 stainless steel\u003c\/strong\u003e piping to establish an unrestricted, high-velocity flow path for the turbocharged \u003cstrong\u003eFA24F\u003c\/strong\u003e boxer engine. By removing the restrictive factory baffling, thermal dissipation at the rear subframe is accelerated and gas evacuation improves. Built with robust, precision TIG-welded hanger rods that locate directly into the factory rubber isolators, this kit includes polished exhaust tips engineered to sit centered within the OEM rear bumper cutouts. Direct-fit connection flanges mate to your factory mid-pipe section without cutting or custom fabrication.\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 polished tips\u003c\/li\u003e\n  \u003cli\u003eFlange mounting hardware kit\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;\"\u003e2019-2025 Subaru Ascent\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;\"\u003eFA24F 2.4L Turbo \/ WM\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;\"\u003e260 hp \/ 277 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-MD098-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\u003e2019-2025 Subaru Ascent (Base, Premium, Onyx Edition, Limited, Touring) 2.4L Turbo AWD\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 WM Ascent?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct bolt-on fit for the 2019-2025 Subaru Ascent equipped with the \u003cstrong\u003eFA24F\u003c\/strong\u003e 2.4L turbocharged engine. \u003cstrong\u003eThis kit does not fit other Subaru models or naturally aspirated platforms.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eDo I need an aftermarket ECU tune after installing this axle-back?\u003c\/h4\u003e\n\u003cp\u003eNo, an ECU calibration is not required because this system installs downstream of all catalytic converters and O2 sensors, preserving factory emissions control and preventing check engine lights.\u003c\/p\u003e\n\n\u003ch3\u003eThe Subaru Boxer Sound Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to unlock the distinct acoustic profile of the turbocharged \u003cstrong\u003eFA24F\u003c\/strong\u003e, this 304 stainless steel system provides long-term corrosion resistance and an uncompromising tone built for daily driving and trail excursions alike.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68046632583416,"sku":"DS-EXVZ8QNDN","price":389.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/axle-back-exhaust-for-subaru-ascent-2019-2025-2-4l-1.jpg?v=1794267395","url":"https:\/\/performancechiptuning.com\/de\/products\/axle-back-exhaust-for-subaru-ascent-2019-2025-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
