Valvetronic Designs 2021-2025 BMW 3 Series G8x M3 / M4 Valved Sport Exhaust System
BMW G80 M3 / G82-G83 M4 Exhaust System Single 3.5" Equal-Length Mid-Pipe + Optional Valved Axle-Back (T304 Stainless or Grade 5 Titanium) Overview The G80/G82/G83 is a phenomenal M car – its soundtrack just needs to catch up. Our single 3.5" equal-length mid-pipe unlocks the character the S58 deserves without requiring changes to the OEM rear section. Add the Valvetronic Designs valved axle-back for even more presence and control. Compatible with OEM downpipes or free-flow front pipes, this system is engineered to deliver a higher-pitch, refined note with zero check-engine lights.
