Trüpower Golf MK7 1.4 TSI EA211 De-cat Downpipes allow your 1.4 EA211 TSI turbo charged engine to breathe the way it was meant to breathe. Stock downpipes are equipped with catalytic converters which restrict airflow and reduce the output of the turbo charger. Trüpower Motorsports downpipes are a 2 piece system without a catalytic converter to ensure a massive increase in airflow. Most factory downpipes are narrow which also restricts airflow and reduce potential horsepower. Trüpower Golf MK7 1.4 TSI EA211 downpipes use larger diameter stainless steel piping to ensure increased air flow. Smooth, unrestricted air flow will improve engine performance, improve engine and fuel efficiency, increase throttle response for faster acceleration and maximize power output of your Golf MK7 EA211 turbo engine.
