Valvetronic Valved Sport Exhaust System with 400-Cell Catted Downpipes - Brushed Stainless Steel - 4 1x1 Carbon Fiber Tips - 4.0 Outlet (2020-2025 BMW G80 M3 / G82 M4) BMW.G8X.M3.VSES.400C.BR.RC
Take your S58-powered BMW to the next level with the Valvetronic Valved Sport Exhaust System with 400-Cell Catted Downpipes for the 2020-2025 BMW G80 M3 and G82/G83 M4. Designed to dramatically improve the factory exhaust character, this system delivers a smoother, sharper, and more exotic motorsport-inspired tone while improving exhaust flow, throttle response, and overall driving engagement.
The system is centered around a single 3.5-inch equal-length mid-pipe engineered to optimize exhaust pulse balance and improve exhaust scavenging throughout the RPM range. Combined with the included 400-cell catted downpipes, the setup produces a refined high-frequency exhaust note with improved responsiveness and cleaner sound characteristics compared to unrestricted race-style exhaust systems.
Constructed from premium T304 stainless steel, the system provides excellent durability, optimized flow, and reduced weight compared to the factory exhaust. Finished with aggressive 4.0-inch 1x1 carbon fiber quad exhaust tips, the setup delivers a high-end exotic-inspired appearance that perfectly complements the styling of the G80 M3 and G82/G83 M4.
