O2 sensor bungs and brackets match the ones present on the stock component.\u003cbr\u003e\u003cbr\u003eThe installation of these turbo downpipes involves the elimination of the stock catalytic converter, allowing a great improvement of the free flowing characteristics of the exhaust right downstream of the turbochargers. This brings a sensible performance gain, a reduction in the local temperature and mechanical stress.\u003cbr\u003e\u003cbr\u003eThe use of free flowing turbo downpipes is highly recommended on tuned cars.\u003cbr\u003e\u003cbr\u003eAs the catalytic converter has been removed, the O2 sensors placed after it on the stock unit will read incorrect values, and this will turn on the CEL (check engine light) on the dash.\u003cbr\u003eTo solve this issue there are three possible solutions:\u003cbr\u003e-To extend the O2 sensor wires, plugging the sensors into the bungs placed after the metallic sports cats on the Supersprint front pipes.\u003cbr\u003e-To deactivate the sensors by reprogramming the ECU\u003cbr\u003e-To fit \"microcats\" between the sensors and the bungs on the downpipes.\u003cbr\u003eFor more information contact our customer services or ask a competent tuner.\u003c\/p\u003e","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":53514620043601,"sku":"980611","price":832.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/6371\/5665\/files\/Supersprint-Turbo-Downpipe-With-De-cat-BMW-E8X-135i-_-E9X-3-Series-335i-_N55_-Supersprint-159698785.jpg?v=1776086492","url":"https:\/\/therossocorsacollective.com\/products\/supersprint-turbo-downpipe-with-de-cat-bmw-e9x-3-series-335i-n55","provider":"The Rosso Corsa Collective","version":"1.0","type":"link"}
