Remus switchable rear back boxes for RS4 Avant B8 4.2 V8

Give your RS4 Avant B8 the rich, motorsport-inspired soundtrack it deserves while keeping a discreet OE look. This premium Remus rear section replaces the factory rear boxes with a left and right pair that work seamlessly with the car’s original valve flap control and keep your stock oval tail trims. You get a deeper, more purposeful tone when the flaps are open and calm motorway manners when they are closed, plus smoother flow and sharper throttle response. Built in stainless steel, hand finished in Austria and EU road legal, it is the enthusiast’s choice for a refined Audi V8 sound upgrade on non particulate filter cars.

Why owners choose this upgrade

• Uses the car’s factory flap control for a switchable soundtrack without extra electronics
• Retains the original tailpipe finishers for a true OE-plus appearance
