It is a Federal \/ EPA direct-fit unit, making it a practical choice for replacing a worn or restricted converter while maintaining the original exhaust layout. The DIRECT FIT line is produced with automated workstations, spinner welding equipment, and high-speed manufacturing processes to help keep dimensions aligned with OE requirements.\u003c\/p\u003e\u003cp\u003eThe converter uses a standard catalyst design and does not include O2 sensor ports. Inlet and outlet connections are welded in place, with a 3-bolt welded inlet and 2-bolt welded outlet. This makes it a focused replacement for the specified Buick Regal rear exhaust application, and part number 50526 is the reference to use when matching the correct unit.\u003c\/p\u003e\u003ch2\u003eCommon Problems This Part Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFailed emissions testing caused by a restricted or inefficient rear converter\u003c\/li\u003e\n\u003cli\u003eCheck engine light conditions related to catalytic converter performance\u003c\/li\u003e\n\u003cli\u003eExhaust flow loss from a damaged or deteriorated converter core\u003c\/li\u003e\n\u003cli\u003eRattling or internal breakage inside the converter housing\u003c\/li\u003e\n\u003cli\u003eFitment issues when replacing the original rear undercar converter on a 2011 Buick Regal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle is a 2011 Buick Regal with the rear undercar converter configuration before ordering. This part uses welded inlet and outlet connections, so the existing exhaust setup should be inspected for flange condition and alignment before installation. Because there are no O2 sensor ports on this converter, confirm the vehicle’s sensor placement matches the original exhaust design. For best results, compare the original converter dimensions and connection style to Eastern Convertors 50526 before installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eEastern Convertors uses automated production methods and OE-dimension manufacturing controls to support consistent fitment and repeatable build quality. The DIRECT FIT line is designed around application-specific exhaust replacement, and the NANO substrate chemistry is used to improve catalyst efficiency through higher loading performance.\u003c\/p\u003e","brand":"Eastern Convertors","offers":[{"title":"Default Title","offer_id":52954952073397,"sku":"BBPJ-50526","price":579.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/EA_50526_Fro.jpg?v=1786344220","url":"https:\/\/www.partcatalog.com\/products\/eastern-convertors-50526-catalytic-converter-rear","provider":"PartCatalog","version":"1.0","type":"link"}
