Remus Valved Axle-Back Rear Section Exhaust for BMW M4 F82 LCI Coupe (2016-2018) S55 – Quad 98mm Tailpipes (Carbon/Black Chrome) – Stainless Steel, ECE Approved – Non-OPF/Non-GPF Performance Sports Back Box/Muffler

Remus valve-controlled rear section with quad 98 mm outlets for BMW M4 F82 LCI 2016 to 2018

Give your facelift BMW M4 F82 the soundtrack and presence it deserves. This Austrian-built Remus rear section replaces the factory back box with a precision engineered, valve-controlled axle-back that delivers a deeper, motorsport-inspired tone under load while remaining civil in everyday driving. It keeps the factory valve operation for seamless integration and a refined, drone-free commute, then opens up for a fierce, characterful soundtrack when you want it.

Compatibility note: for pre-OPF vehicles only. Not suitable for GPF equipped cars.

Sound and driveability

In Comfort the car remains civil with a clean, bass-rich note. Switch to Sport modes and the valves open for a harder-edged, track-inspired bark with crisp upshift cracks and a fuller tone that lets the S55B30 sing. No unwanted drone, just a mature, performance-led soundtrack.

Craftsmanship you can trust
