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
