Remus Valve-Controlled Sports Exhaust, Non-Resonated, Quad 84 mm Tailpipes for Audi RS5 B9 F5 Coupe 2.9 TFSI V6 DECA (2017 onwards) | Stainless Steel | EEC Homologated | For non-GPF cars

Give your B9 RS5 the soundtrack and presence it deserves. This Remus valve-controlled system replaces the rear section after the downpipes with a free-flow, non-resonated setup and stunning quad 84 mm outlets. Handcrafted in Austria from premium stainless steel and EEC approved as stated by the manufacturer, it delivers a deep, motorsport-inspired tone with OEM-plus fit and finish. It looks right, it sounds right and it transforms the driving experience without compromise.

Key advantages

• Non-resonated, straight-through internals for a louder, richer note and enhanced character
• Integrated valve flaps retain factory valve control for everyday refinement or full-bore sound
• Optimised gas flow for reduced back pressure and sharper response
• Durable, shot-blasted stainless steel with precision welds and a premium surface finish
• Direct-fit to OEM mounting points, connection after the downpipes for a clean install
• Handmade in Austria by Remus for outstanding quality, reliability and longevity
• EEC homologation for road use as stated by the manufacturer

We have installed this setup for RS5 owners and the feedback has been superb. Customers love the deeper tone, the lack of drone with valves closed and the aggressive soundtrack when opened. Fitment has been seamless and the quad outlets fill the diffuser beautifully for a factory-plus look.
