Valvetronic Valved Sport Exhaust System with 400-Cell Catted Downpipes - Brushed Stainless Steel - 4 Brushed Steel Tips - 3.5 Outlet (2020-2025 BMW G80 M3 / G82 M4) BMW.G8X.M3.VSES.400C.BR.BRSH
Unlock the full sound and performance potential of the S58 engine with the Valvetronic Valved Sport Exhaust System with 400-Cell Catted Downpipes for the 2020-2025 BMW G80 M3 and G82/G83 M4. Engineered to dramatically improve exhaust tone, flow, and overall driving character, this system transforms the muted factory exhaust into a sharper, smoother, and more motorsport-inspired setup while maintaining refined daily drivability through fully controllable valve operation.
At the center of the system is a single 3.5-inch equal-length mid-pipe designed to improve exhaust pulse balance and optimize exhaust flow throughout the RPM range. Combined with the included 400-cell catted downpipes, the system enhances throttle response, increases overall exhaust efficiency, and delivers a more refined high-frequency exhaust note without the excessive harshness commonly associated with unrestricted systems.
Constructed from premium T304 stainless steel, this setup combines durability, optimized flow, and significant weight savings compared to the factory exhaust. Finished with aggressive 3.5-inch brushed steel quad exhaust tips, the system delivers an OEM-plus appearance that perfectly complements the aggressive styling of the G8X platform.
