Remus Non-Resonated Valved Performance Cat-Back Exhaust for Audi S3 (8V) 2.0 TFSI Quattro 2016-2018 | Quad 84mm Tips | L/R Quad Exit | 76mm | OE Valve Control | Stainless Steel | ECE Approved

Remus Sports Catback for Audi S3 8V 2.0 TFSI quattro 2016 to 2018 – valve‑actuated, quad exit, EU road legal

Give your S3 the soundtrack it deserves. This Remus performance rear system replaces the factory catback with a straight‑through, un‑silenced centre section and switchable flap control, delivering a richer, more purposeful note without the drone. Crafted in Austria from premium stainless steel with shot‑blasted finish, the kit features four 84 mm tailpipes and free‑flowing 76 mm pipework for reduced back pressure and sharper throttle response. It bolts to the original hangers and uses the car’s existing valve motors and electronics, so comfort modes stay refined and dynamic settings come alive. ECE type approved for peace of mind on UK and European roads.
