The CTS Turbo single mid pipe kit for the BMW M3/M4 with the S58 engine is designed for drivers who want a more pronounced exhaust sound and improved exhaust gas flow without unnecessary cabin drone. It is a non-resonated design.
The factory mid pipe with two resonators restricts sound and exhaust gas flow. The single mid pipe replaces it with a smooth-flowing 89 mm (3.5″) stainless steel pipe, eliminating the factory restriction and giving the S58 engine a deeper, cleaner sound.
Key features
- 89 mm (3.5″) single pipe – replaces the factory twin mid pipe for a deeper, cleaner exhaust sound.
- CNC mandrel bending – continuous radii reduce the need for welding.
- SS304L stainless steel construction – precise welds and a custom fit.
- Easy installation – only two cuts are required at the factory-marked indented sections; installation is simple and reversible.
- Compatible with factory and upgraded downpipes.
- A stainless steel exhaust tunnel brace is included, designed based on the factory part.
- Precise fitment for simple installation.
