CTS Turbo B9 Audi A4 2.0T Catback Exhaust System (2017-2019)

This CTS Turbo catback exhaust system is purpose-built for B9 generation Audi A4 2.0T models spanning 2017 through 2021. The complete catback construction replaces restrictive factory components from the catalytic converter back, improving exhaust flow characteristics while delivering a refined, sporty exhaust note. Mandrel-bent tubing ensures consistent internal diameter throughout the system, reducing backpressure without drone. Designed for direct bolt-on installation, this system suits workshops performing comprehensive engine tuning packages where exhaust upgrades complement ECU recalibration and other performance modifications on the EA888 Gen3 platform.
