Remus Valved Backbox / Axle-Back Exhaust for Audi S3 8V 2.0 TFSI Quattro (2018+, Non GPF/OPF) - OE Valve Compatible Sports Rear Silencer/Muffler, Quad 4x84mm Tailpipes, 100% Stainless Steel, ECE/EEC Approved, Road Legal

Remus sports backbox for Audi S3 8V – precision-built, valve compatible and EU approved

Give your S3 8V the soundtrack and quality it deserves. This Remus valved rear section replaces the factory rear box, integrates with the original valve control, and unlocks a deeper, more purposeful tone with reduced back pressure for sharper response. Built in Austria from 100% stainless steel with a durable shot-blasted finish, it is a premium quad-exit upgrade that looks as good as it performs.

We have installed this system at MJ Modifications and the feedback from S3 owners has been outstanding. Customers love the refined valve-on-valve-off character, the perfect fitment, and the high-end finish on the 84 mm tailpipes. If you are searching for a quality sports rear box for a non-GPF Audi S3 8V, this is the one.
