For the performance range topping F40, BMW revived the ‘M135i’ moniker, sporting BMW’s B48 2 litre, 4-cylinder engine. The M135i is shipped from the factory with a muted exhaust sound leading to a very disappointing driving experience. Along with increased performance, Cobra Sport were keen to put the emotion back into the drive with an improved aural and emotional driving experience.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eCobra Sport opted for 3”\/76.2mm stainless steel pipework for the biggest upgrade in terms of performance, flow rate and sound levels. The free-flowing Cobra Sport exhaust setup completely transforms the vehicle and will open up the future tuning possibilities of the BMW M135i (F40).\u003c\/p\u003e\n\u003cp\u003eCobra Sport have transformed the styling of the BMW M135i, creating a quad exit conversion that draws attention to the peachy rear of BMW's hot hatch. With 4\" (101.6mm) carbon fibre quad tips specifically selected to ensure you stand out from the crowd and draw attention to the looks as well as the sound of your M135i.\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe all-new GPF\/PPF-Back quad exit performance exhaust with rear silencer perfectly compliments the 'jack of all trades' character of the M135i. In comfort mode the exhaust valve is closed, allowing the driver to cruise around and eat up the miles in comfort, with just a subtle hint that there is over 300BHP available at the press of the right foot. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eSwitch to Sport mode and the drive of the M135i is transformed, the exhaust valve opens allowing exhaust gases to be split between the rear silencer and a rear silencer by-pass, enhancing the exhaust sound levels and allowing the M135i to sing to its hearts content and recording 91dB at 4,000rpm, an increase of +11.1dB - capturing the motorsport heritage that runs through the veins of the M135i.\u003c\/p\u003e\n\u003cp\u003eCobra Sport has also developed their race box delete performance exhaust for the ultimate thrill seeker. This system takes inspiration from Cobra Sport's venom range by removing the rear silencer and exhaust valves, the race box delete allows for the biggest upgrade in terms of sound levels recording 92.8dB at 4000RPM (+12.9dB) at all times - whilst keeping the factory fit catalyst and GPF (gasoline particulate filter) in place. \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eMedia\u003c\/h2\u003e\n\u003cp\u003eStatic Sound Example - Non-Valved GPF Back with Box Delete\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/WCshiHIpXTE\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eExhaust Talk 03 - GPF Debate - What is a GPF \/ PPF Exhaust Particulate Filter - Improve Exhaust Sound\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/AOBiqIj1U0o?si=a9caHla-z7J2hRfv\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eStatic Sound Example - Valved GPF Back with Rear Box\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/V8IzcZiNDMs\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003eBrand Video - Designed to demand attention, engineered to lead.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/QLwAWwElbJE\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"Cobra Sport","offers":[{"title":"Non-Valved \/ TP116-CF (Carbon Fibre)","offer_id":51029374140755,"sku":"BM157TP116-CF","price":967.81,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/2211\/7715\/files\/BMW-M135i-F40-Quad-Exit-Venom-GPFBack-CobraSport-Exhaust-BM157TP116-CF.jpg?v=1749454281","url":"https:\/\/amdtuning.com\/products\/bmw-m135i-f40-quad-exit-gpf-ppf-back-race-box-delete-m3-style-performance-exhaust","provider":"AMD Tuning","version":"1.0","type":"link"}
