S58 G80 M3/G82/G83 M4 Single Mid Pipe with Brace

The CTS Turbo BMW S58 G80 M3/G82/G83 M4 Single Mid Pipe Kit (non-resonated) is engineered for enthusiasts seeking to unlock a more aggressive exhaust note and enhance exhaust flow without introducing unwanted drone. The original mid-pipe setup features a dual-resonator design that limits both sound and performance. This upgrade replaces it with a seamless, high-flow 89mm (3.5″) stainless steel pipe, effectively eliminating factory bottlenecks and allowing the S58 engine to produce the raw, refined tone it deserves. Constructed from SS304L stainless steel with CNC mandrel bends, this mid-pipe is built for longevity and precise fitment, minimizing welding and ensuring continuous bends for optimal flow. The kit includes a stainless steel exhaust tunnel brace, mirroring the factory design. This single mid-pipe is compatible with both factory and aftermarket downpipes. It is specifically designed for the 2021+ BMW G80 M3 (all models), 2021+ BMW G82 M4 (all models), and 2022+ BMW G83 M4 Convertible (all models). Please note that this component is not compatible with GPF/OPF systems found on ROW (Rest of World) vehicles.
