Remus Valved Cat-Back Performance Exhaust for BMW 5 Series M550i V8 xDrive (G30/G31) 2017+ – Non-Resonated, Quad 102mm Tips – Stainless Steel, ECE/EEC Approved – Sport/Active/Valvetronic Catback Backbox Upgrade (Saloon & Touring, non-OPF/GPF)

Remus Sports System for BMW 5 Series M550i xDrive G30 G31 2017 onwards

Elevate your 5 Series V8 with a premium Austrian-made sports exhaust that unlocks a richer tone, cleaner flow and a sharper driving feel. This non-resonated rear section with flap control replaces the factory system from the catalytic converters back, delivering a deeper soundtrack and reduced backpressure while retaining everyday refinement through the factory valve electronics.

Handcrafted from high grade stainless steel with a shot blasted finish, the Remus setup is built for longevity and performance. We have installed this system on customer cars and our own demonstrators, and the feedback is outstanding. Expect a purposeful cold start, muscular acceleration notes and a refined cruise when the valves are closed. If you are searching for a BMW G30 G31 V8 sound upgrade, a quad exit sports system or a high quality stainless performance exhaust for M550i, this is the enthusiast favourite.
