The CTS Turbo S58 BMW M3/M4 Single Mid Pipe Kit (non-resonated) is designed for enthusiasts looking to unlock a more aggressive exhaust note and improve exhaust flow without unnecessary drone. The factory mid-pipe setup, with its dual-resonator design, restricts sound and performance. Our single mid-pipe replaces it with a smooth, high-flow 89mm (3.5") stainless steel pipe, eliminating the factory bottle-necking and giving the S58 engine the raw, refined tone it deserves. Key Features: Single 89mm (3.5") diameter – Replaces the factory dual mid-pipe for a deeper, cleaner exhaust note CNC mandrel bends - Continuous bends to minimize welding SS304L stainless steel construction – Built to last with precision welds and a perfect fit Easy installation, only two cuts required at the "dimples" marked by the factory – Simple, reversible installation Works with factory and aftermarket downpipes Stainless steel exhaust tunnel brace included - based on the factory part Perfect fitment - hassle-free install Fitment (not compatible with GPF/OPF systems on ROW cars): 2021+ BMW G80 M3 (all) 2021+ BMW G82 M4 (all) 2022+ BMW G83 M4 Convertible (all)
