Remus Valved Cat-Back Sport Exhaust for BMW 5 Series 540i xDrive (G30/G31, B58, 2017+) - Non-Resonated Performance System, Switchable/Active Sound, Quad 102mm Tips - Stainless Steel, ECE Approved - Fits Saloon & Touring (Sedan/Wagon), AWD - No GPF/OPF

Remus valve‑controlled performance system for BMW 540i xDrive G30 G31

Give your 3.0 B58 straight‑six the soundtrack it deserves. This Austrian‑built Remus rear and mid‑section upgrade replaces the centre silencer with a straight‑through path and adds valve‑actuated rear boxes that integrate with the factory electronics. The result is a deeper, more purposeful tone on demand, refined manners when you want quiet cruising, and freer breathing pipework for crisper throttle response.

Crafted from premium stainless steel with a shot‑peened finish, the system is engineered for precise fitment on the BMW 5 Series G30 saloon and G31 estate in 540i xDrive form. It uses the original mounting points for a neat, hassle‑free install and carries ECE type‑approval. This version is for vehicles without a petrol particulate filter.

Real‑world sound and drivability

With the valves closed, the note is subtle for daily use and motorway miles. Open them up and the unsilenced centre delivers a deep, characterful tone with an authentic performance edge. It enhances the rear profile with quad tips and keeps cabin refinement intact when you need it.
