{"product_id":"front-j-pipe-non-resonated","title":"Front J-Pipe - Non-Resonated","description":"The Supersprint Front \"J-Pipe\" - Non Resonated is a precision, direct-fit stainless steel upgrade engineered for the BMW G80 M3, G81 M3, G82 M4 \u0026amp; G83 M4. It replaces the restrictive factory component to free up exhaust flow, sharpen throttle response, and give your BMW a deeper, more purposeful note.\n\nSupersprint has been handcrafting performance exhausts in Mantova, Italy since 1955. Every system is designed and validated on the dyno, using thin-wall stainless steel and carefully sized tubing that raises exhaust gas velocity while protecting mid-range torque. This results in real, usable power gains across the rev range. The J-Pipe features a 100mm cross-section and is constructed from T304 stainless steel with 70mm connecting pipes.\n\nIt is a direct bolt-on fit to the OEM mounting points. Supersprint offers various configurations of this J-Pipe system, including options that delete secondary catalytic converters and OPFs, or modify front and centre mufflers depending on the chosen rear muffler setup.\n\nFitment includes a wide range of BMW G80 M3, G81 M3, G82 M4, and G83 M4 models from 2021 onwards, encompassing variants like M3\/M4, M3\/M4 xDrive, M3\/M4 Competition, M3\/M4 CS, M4 CSL, and M3\/M4 \"M Performance\" models, with specific considerations for models equipped with OPF. It is noted that all products sold by R44 Performance Limited are designated RACE ONLY and for competition or off-road use only.","brand":"Supersprint","offers":[{"title":"Default Title","offer_id":52873190015288,"sku":"SUP.527712 SUP.989244","price":1953.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/front-j-pipe-non-resonated","provider":"MOTORMIA","version":"1.0","type":"link"}
