The CTS Turbo 3-inch stainless steel downpipe is designed for the first-generation Audi TT 225Q. The factory downpipe heavily restricts exhaust gas flow, which is particularly noticeable on vehicles with optimised software. The replacement downpipe enables smoother exhaust gas flow and is suitable for higher-performance builds.
The modular design simplifies catalytic converter installation, while the smooth transitions help ensure efficient exhaust gas flow.
Important: not suitable for convertibles.
