Milltek Downpipe (Primary Hi-Flow Sports Cat + Turbo Elbow) – 76mm (3″)

Audi RS3 Sportback (8V; 2015-) 2.5 TFSI Quattro



This system replaces the primary OEM catalyst for our Hi-Flow Sports catalyst. The lower density of the sport catalyst allows for exhaust gases to be less restricted and pass through more effectively. The sports catalyst comes equipped with a Turbo elbow which allows for an improved connection to the vehicle’s turbo. The wide diameter of the outlet allows the turbo to “spool” sooner increasing performance and improving throttle response.
