MillTek Audi RS3 Sportback Primary Sport Cat Turbo Elbow (2015-2017) Style:Default Please review our Tuning GuideThis system replaces the primary OEM Catalyst for our Hi Flow Sport Catalyst. The lower density of the Sport Catalyst allows for exhaust gases to be less restricted and pass through more effectively. The Sport 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. Requires Stage 2
