Choose valved or non-valved, with 4\" (101.6mm) stainless steel or carbon fibre tailpipes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e This system has no rear silencer and will be loud. Valved versions retain the factory exhaust valves, so the tone still changes between quieter and louder settings as you switch drive modes. Non-valved versions remove the exhaust valves, so the sound will no longer change with drive modes. This will not harm the running of the car.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e3\" (76.2mm) pipework from the GPF backwards, replacing the centre and rear sections\u003c\/li\u003e\n\u003cli\u003eRace box delete - no rear silencer\u003c\/li\u003e\n\u003cli\u003eKeeps the factory catalyst and GPF\u003c\/li\u003e\n\u003cli\u003eTested at 73.5dB at idle (+10.5dB) and 95.1dB at 3,800rpm (+13.1dB)\u003c\/li\u003e\n\u003cli\u003eChoice of 4\" (101.6mm) stainless steel or carbon fibre tailpipes\u003c\/li\u003e\n\u003cli\u003eAll relevant fittings and gaskets are supplied.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eBMW F40 M135i xDrive (2019+)\u003c\/li\u003e\u003c\/ul\u003e","brand":"Cobra Sport","offers":[{"title":"Valved \/ TP19","offer_id":55684140728696,"sku":"BM129TP19","price":1027.2,"currency_code":"GBP","in_stock":true},{"title":"Valved \/ TP38","offer_id":55684140761464,"sku":"BM129TP38","price":1027.2,"currency_code":"GBP","in_stock":true},{"title":"Valved \/ TP106-CF Carbon Fibre","offer_id":55684140794232,"sku":"BM129TP106-CF","price":1176.96,"currency_code":"GBP","in_stock":true},{"title":"Valved \/ TP107-CF Carbon Fibre","offer_id":55684140827000,"sku":"BM129TP107-CF","price":1176.96,"currency_code":"GBP","in_stock":true},{"title":"Non-Valved \/ TP19","offer_id":55684140859768,"sku":"BM121TP19","price":770.4,"currency_code":"GBP","in_stock":true},{"title":"Non-Valved \/ TP38","offer_id":55684140892536,"sku":"BM121TP38","price":770.4,"currency_code":"GBP","in_stock":true},{"title":"Non-Valved \/ TP106-CF Carbon Fibre","offer_id":55684140925304,"sku":"BM121TP106-CF","price":920.16,"currency_code":"GBP","in_stock":true},{"title":"Non-Valved \/ TP107-CF Carbon Fibre","offer_id":55684140958072,"sku":"BM121TP107-CF","price":920.16,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0765\/4670\/3651\/files\/cobra-sport-gpf-back-exhaust-race-box-delete-bmw-f40-m135i_1.jpg?v=1790693963","url":"https:\/\/www.evolveautomotive.co.uk\/de\/products\/cobra-sport-gpf-back-exhaust-race-box-delete-bmw-f40-m135i","provider":"Evolve Automotive","version":"1.0","type":"link"}
