The resonator body measures 12 inches long with a round 5 x 5 inch profile, and the assembly uses precise tuning to support original-equipment sound levels and steady exhaust flow. If you are replacing a worn or damaged exhaust section on a 2008-2015 Scion xB, part number 54842 provides the correct fitment format for that application.\u003c\/p\u003e\u003cp\u003eThis part cross-references AP Exhaust 7546 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExhaust noise from a damaged resonator section\u003c\/li\u003e\n\u003cli\u003eRust or corrosion in the pipe or body\u003c\/li\u003e\n\u003cli\u003eFitment problems caused by a bent or failing exhaust assembly\u003c\/li\u003e\n\u003cli\u003eLoss of OE-style exhaust tone after replacement\u003c\/li\u003e\n\u003cli\u003eRestricted exhaust flow from a deteriorated resonator assembly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the inlet flange style, outlet diameter, and overall length before installation. This assembly uses a 2-bolt welded flange inlet and a spout outlet, so matching the existing exhaust connection points is important for proper alignment on the Scion xB. Check surrounding hangers, clamps, and adjoining exhaust components for wear before final installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker designs this resonator to fit, perform, and sound like the original system, using tuning methods aimed at OE-style exhaust characteristics and consistent flow.\u003c\/p\u003e","brand":"Walker","offers":[{"title":"Default Title","offer_id":52859186708661,"sku":"BDCN-54842","price":133.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/WK_54842_Fro.jpg?v=1784872514","url":"https:\/\/www.partcatalog.com\/products\/walker-54842-exhaust-resonator-and-pipe-assembly","provider":"PartCatalog","version":"1.0","type":"link"}
