{"product_id":"b58-catless-downpipe","title":"IBOAUTO B58 Gen 1 4.5\" Catless Downpipe","description":"\u003cp\u003eA 4.5\" catless downpipe for the Gen 1 B58 in the 340i, 440i, M240i and 540i. It swaps the restrictive factory downpipe and catalytic converter for a straight-through 304 stainless pipe, so the turbo spools sooner and the car makes more power once it's tuned. A braided flex section soaks up engine movement, and the mounting bracket comes in the box.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e4.5\" 304 stainless, 1.5 mm wall\u003c\/li\u003e\n\u003cli\u003eStraight-through, no catalytic converter\u003c\/li\u003e\n\u003cli\u003eBraided flex section\u003c\/li\u003e\n\u003cli\u003eBolt-on, no cutting or welding\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IBOAUTO","offers":[{"title":"Brushed stainless \/ B58 Gen 1","offer_id":67893535637810,"sku":"100007928:-6#silver;191284006:-7#L36cmW6cmH6cm","price":349.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/2064\/2354\/files\/H78db74c6d85845808148cfb62e12501aT_e82dd868-6a43-492e-90de-8f91407763b1.webp?v=1790818550","url":"https:\/\/iboautomotive.com\/products\/b58-catless-downpipe","provider":"IBOAUTOMOTIVE","version":"1.0","type":"link"}
