The CTS Turbo midpipe for BMW F-series models with the B58 Gen.1 engine is designed to improve exhaust gas flow, engine response and the distinctive, deeper sound characteristic of the B58 engine. The factory midpipe has significant sound suppression, so this high-flow replacement improves throttle response, speeds up turbo spool and creates a deeper, more refined exhaust sound.
It is made from T304 stainless steel and allows direct installation using all factory mounting points. It is compatible with OEM components and provides noticeable sound and performance improvements without annoying droning or unwanted resonances.
It is suitable for both standard and software-tuned vehicles. The kit is intended for BMW 340i and 440i F-series models with the B58 Gen.1 engine and is not compatible with B58TU (Gen.2) engines fitted to later G-series models.
