Milltek OPF/GPF-Back Valved Axle-Back/Backbox Bypass Exhaust, JET-115 Carbon Tips, for BMW M8 & M8 Competition F91 F92 4.4 V8 Twin Turbo 2020+ Coupe/Convertible | 8 Series S63 | T304 Stainless | Rear Muffler Delete Sound | OPF/GPF Models Only

Milltek rear section with active valves and JET-115 carbon tailpipe finishers for BMW M8 and M8 Competition F91 F92 2020 onwards

Give your S63-powered BMW 8 Series the soundtrack it deserves. This particulate filter back rear section from Milltek transforms the tone of OPF and GPF equipped M8 models without touching the factory petrol particulate filter. Expect a deeper, richer V8 character, sharper response and a motorsport look thanks to the premium JET-115 carbon fibre tips. Built in Britain from T304 stainless steel and engineered for a precise OEM plus fit, it is the go to exhaust upgrade for F91 Convertible and F92 Coupé owners who want drama when they want it and refinement when they need it.

Why enthusiasts choose this system

• Crafted from high grade T304 stainless for long term durability and corrosion resistance
• Free flowing, mandrel bent tubework to aid gas velocity and throttle response

• Stunning JET-115 carbon fibre tailpipe finishers for an aggressive OEM plus rear end
• Acoustically tuned for a clean V8 note with minimal cabin boom
• Direct fit to OPF and GPF vehicles while retaining the factory particulate filter
