Milltek Sport V2 Valved Exhaust System For BMW E90, E92 & E93 M3 4.0 V8

Bring your BMW E9X M3 to life with the Milltek Sport V2 Valved Exhaust System, the ultimate upgrade for those who want power, sound, and sophistication in one package. Precision-engineered in the UK, this advanced valved cat-back exhaust is specifically designed for the S65 4.0-litre naturally aspirated V8 engine found in the E90, E92, and E93 M3 models.Milltek’s new V2 design takes everything enthusiasts loved about the original and refines it for the modern era. Using the latest valving technology, the system features electronically controlled valves and includes two wireless remote controllers, allowing you to instantly toggle between subdued and aggressive exhaust modes.With the valves closed, the system delivers a deep yet refined tone – perfect for daily driving or early morning starts. Open the valves, and the true character of the S65 shines through with an intense, motorsport-inspired growl that builds through the rev range. The result is a perfectly balanced system that delivers OEM-level refinement with the raw emotion of a track-ready exhaust.Engineering and ConstructionBuilt from premium T304L stainless steel, the Milltek Sport V2 Exhaust System is designed to withstand years of use under both street and track conditions. Each component is CNC mandrel-bent to ensure consistent pipe diameter and minimal flow restriction, helping to reduce back pressure and improve throttle response.The system features a 70mm pipe diameter – carefully tuned to maximise performance while maintaining optimal back pressure for smooth power delivery. Each weld is TIG-finished by hand, ensuring superior strength and a flawless appearance.The GT-80 Cerakote black tailpipes offer a striking, modern finish that perfectly complements the M3’s aggressive design. The twin 80mm outlets fill the factory diffuser beautifully and add a premium motorsport aesthetic.Performance and SoundThis system is designed to enhance both drivability and auditory emotion. On the dyno, Milltek’s high-flowing design has been shown to improve torque delivery and throttle response, particularly in the mid-to-high rev range where the S65 engine thrives.When valves are open, exhaust gases flow freely through a reduced-resistance path, producing a spine-tingling, high-revving tone that perfectly suits the M3’s naturally aspirated powerband. Close the valves, and internal baffling routes gases through the silencers, resulting in a quieter, more civilised tone ideal for cruising or long-distance journeys.Installation and CompatibilityThis cat-back system is a direct replacement for the OEM exhaust and can be installed without permanent modifications. Milltek supplies adapters to connect directly to the factory mid-section, ensuring perfect fitment and easy installation.Installation typically takes 3–4 hours, including removal of the original system. All necessary components, clamps, and hardware are included.Technical SpecificationsSystem Type: Cat-Back (Valved)Pipe Diameter: 70mmMaterial: T304L Aircraft-Grade Stainless SteelTailpipe Design: GT-80 Cerakote Black Tips (MSTIP320)Valving System: Electronically Controlled w/ 2 Remotes (MSVS065)Installation Time: 3–4 HoursCountry of Manufacture: United KingdomRace Product: NoE-Marked: NoBox Dimensions: 130 × 40 × 30 cm – 29 kgKit ContentsLH Axle Pipe – MSBM454RH Axle Pipe – MSBM455LH Rear Silencer – MSBM456RH Rear Silencer – MSBM457Valved Outlets – MSBM458GT-80 Cerakote Black Tailpipes – MSTIP320Valve Controller with 2x Remote Controllers – MSVS065OE Adapters – F5098Key BenefitsTwo driving modes: Switch between quiet and loud at the touch of a buttonAuthentic V8 tone: Deep and rich at idle, ferocious at high RPMLightweight stainless construction: Reduces overall system weight vs OEMEnhanced throttle response and power deliveryCorrosion-resistant and handcrafted for precision fitmentDirect bolt-on installation – no cutting or welding requiredCompatibilityBMW E90 M3 (Sedan)BMW E92 M3 (Coupe)BMW E93 M3 (Convertible)All equipped with the 4.0-litre V8 S65 engine
