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

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)
