After the turbos, the factory downpipes and their catalytic converters are the biggest restriction in the exhaust. These replace them with mandrel-bent, TIG-welded 304 stainless and a cast V-band flange at each turbo, so the turbos spool sooner and the car sounds deeper and louder once it's tuned.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e3\" mandrel-bent 304 stainless\u003c\/li\u003e\n\u003cli\u003eTIG welded, cast V-band turbo flanges\u003c\/li\u003e\n\u003cli\u003eStraight-through, no catalytic converters\u003c\/li\u003e\n\u003cli\u003eReuses the factory O2 sensors\u003c\/li\u003e\n\u003cli\u003eBolt-on, no cutting or welding\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IBOAUTO","offers":[{"title":"F80 \/ F82 \/ F87","offer_id":67890633408818,"sku":"200257284:-1#OEM","price":549.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/2064\/2354\/files\/Aad402aeed162455fb64f59e4322cf2f2t.webp?v=1790776051","url":"https:\/\/iboautomotive.com\/products\/s55-3-inch-catless-downpipes","provider":"IBOAUTOMOTIVE","version":"1.0","type":"link"}
