CTS TURBO BMW F-series 340i/440i B58 GEN1 Midpipe Upgrade

The CTS Turbo midpipe upgrade replaces the restrictive factory component on BMW F-Series 340i and 440i models equipped with the B58 Gen1 engine. Engineered for improved exhaust flow, this direct-fit midpipe reduces backpressure while enhancing throttle response and delivering a deeper exhaust note. Constructed from high-grade materials to withstand demanding conditions, it's designed for workshops tuning these platforms. Compatible with both rear-wheel drive and xDrive variants from 2016 through 2019 model years, providing a straightforward installation for performance-focused B58 builds.
