{"product_id":"bmw-gen3-b58-400-cell-catted-downpipes","title":"BMW GEN3 B58 400 Cell Catted Downpipes","description":"Valvetronic Designs 400-Cell Catted Downpipe for the BMW B58 Gen 3 platform enhances performance while retaining a catalytic converter for improved street usability.\r\n\r\nThe high-flow 400-cell metallic catalyst reduces exhaust restriction, allowing quicker turbo spool and stronger mid-range power delivery. Compared to factory components, this upgrade delivers improved sound and responsiveness while helping maintain a refined exhaust profile.\r\n\r\nManufactured from high-grade stainless steel and engineered for direct bolt-on installation, this downpipe is built for durability and daily-driven reliability. Tuning may be required to prevent check engine lights and optimize performance.\r\n\u003cul\u003e\t\u003cli\u003eHigh-flow 400-cell metallic catalyst\u003c\/li\u003e\r\n\t\u003cli\u003eimproved spool and throttle response\u003c\/li\u003e\r\n\t\u003cli\u003ereduced backpressure\u003c\/li\u003e\r\n\t\u003cli\u003eOEM-style fitment\u003c\/li\u003e\r\n\t\u003cli\u003estainless steel construction\u003c\/li\u003e\r\n\t\u003cli\u003edeeper exhaust tone\u003c\/li\u003e\r\n\t\u003cli\u003ereduced odor vs catless\u003c\/li\u003e\r\n\t\u003cli\u003edesigned to minimize CEL with tuning.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eAttributes:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eBrand Name: \u003c\/b\u003eValvetronic Designs\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eGTIN: \u003c\/b\u003e00810201226433\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eFinish: \u003c\/b\u003eBrushed\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eInstallation Notes: \u003c\/b\u003eOEM Replacement\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eMaterial: \u003c\/b\u003eStainless Steel\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eOutlet Quantity: \u003c\/b\u003e1\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eWhat is Included: \u003c\/b\u003eDownpipe(s) \u0026amp; Hardware\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eExtended Information:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eCountry of Origin: \u003c\/b\u003eCN\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eEmissions : \u003c\/b\u003eEPA Eligible\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003ePacking Information:\u003c\/h3\u003e\r\n\u003cp\u003e\u003c\/p\u003e\u003cul\u003e\r\n\u003cli\u003e\n\u003cb\u003eQuantity of Each: \u003c\/b\u003e1\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003ePackage UOM: \u003c\/b\u003eEA\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eDimension: \u003c\/b\u003e25.75 x 13.5 x 9 inches\u003c\/li\u003e\r\n\u003cli\u003e\n\u003cb\u003eWeight: \u003c\/b\u003e14.5 POUNDS\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cdiv id=\"sema-product-fitment\" class=\"product__accordion accordion fitment\"\u003e\u003c\/div\u003e","brand":"Valvetronic Designs","offers":[{"title":"Default Title","offer_id":66757563908141,"sku":"JZYF-BMW.B58.GEN3.FF.400C.BR","price":3999.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0646\/2780\/2157\/files\/B58_20DP_20Photo_20Prim.png?v=1779556871","url":"https:\/\/montgomeryparts.com\/products\/bmw-gen3-b58-400-cell-catted-downpipes","provider":"Montgomery Parts","version":"1.0","type":"link"}
