With fewer welded joints, the design helps reduce turbulence and potential leak points while improving strength, heat resistance, and durability. The set retains the required oxygen-sensor ports and uses an integrated flex section to accommodate engine movement and thermal expansion.\u003c\/p\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBMW G80 \/ G81 M3 - S58 engine\u003c\/li\u003e\n\u003cli\u003eBMW G82 \/ G83 M4 - S58 engine\u003c\/li\u003e\n\u003cli\u003eBMW G87 M2 - S58 engine\u003c\/li\u003e\n\u003cli\u003eLeft-hand-drive and right-hand-drive vehicles, subject to vehicle configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e89 mm straight-through catless design\u003c\/li\u003e\n\u003cli\u003e304 stainless-steel construction\u003c\/li\u003e\n\u003cli\u003eHydroformed one-piece main sections for smoother flow and fewer welds\u003c\/li\u003e\n\u003cli\u003eIntegrated flex section and oxygen-sensor ports\u003c\/li\u003e\n\u003cli\u003eReduced exhaust restriction and improved turbo response\u003c\/li\u003e\n\u003cli\u003eMore aggressive turbo and exhaust sound\u003c\/li\u003e\n\u003cli\u003eIncludes left and right downpipes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eImportant Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFOR CLOSED-COURSE COMPETITION \/ TRACK USE ONLY.\u003c\/li\u003e\n\u003cli\u003eNot intended for use on public roads where removal of emissions equipment is prohibited.\u003c\/li\u003e\n\u003cli\u003eProfessional installation and suitable ECU calibration are recommended.\u003c\/li\u003e\n\u003cli\u003ePlease confirm compatibility before ordering, especially for OPF\/GPF-equipped or modified vehicles.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Racing Lab","offers":[{"title":"Default Title","offer_id":48324138336409,"sku":null,"price":100.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/0651\/8425\/files\/51.png?v=1784281817","url":"https:\/\/racinglabshop.com\/products\/racing-lab-89-mm-catless-downpipes-bmw-s58","provider":"Racing Lab","version":"1.0","type":"link"}
