Product description:
The EG/ECE 4" (101.6 mm) downpipe from HPerformance was developed specifically for the 2.5 TFSI DAZA engine in the Audi RS3 8V facelift and Audi TT RS 8S.
At its core is a large, high-performance ceramic catalytic converter with integrated thermal insulation and high filtration capacity. Flow-optimized inlet and outlet funnels complement the flow-optimized piping throughout the system.
Thanks to EC/ECE approval, the downpipe does not require registration within the approved scope of use. The approval document is included with the shipment. Installation is plug-and-play, with no adjustments to the engine control unit required. An adjustable bracket ensures a precise fit.
