Valvetronic Valved Sport Exhaust System with 400-Cell Catted Downpipes - Brushed Stainless Steel - 4 Black Tips - 3.5 Outlet (2020-2025 BMW G80 M3 / G82 M4) BMW.G8X.M3.VSES.400C.BR.BLK
Upgrade the sound and performance of your S58-powered BMW 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 unlock the hidden character of the G8X platform, this system transforms the muted factory exhaust note into a sharper, smoother, and more aggressive motorsport-inspired tone while maintaining refined daily drivability through fully controllable valve operation.
The system is built around a single 3.5-inch equal-length mid-pipe engineered to improve exhaust pulse balance and optimize exhaust flow throughout the RPM range. Combined with the included 400-cell catted downpipes, the setup improves throttle response, enhances exhaust efficiency, and delivers a cleaner, more refined sound profile compared to unrestricted race-style systems.
Constructed from premium T304 stainless steel, the system offers exceptional durability, improved exhaust flow, and noticeable weight savings compared to the factory setup. Finished with aggressive 3.5-inch black quad exhaust tips, the setup adds a stealth-inspired motorsport appearance that perfectly complements the aggressive styling of the G80 M3 and G82/G83 M4.
