Remus BMW M850i xDrive G15 Coupe Non-Resonated Racing Cat-Back/GPF-Back Centre Section for GPF Models, 2018+, N63B44 4.4 V8, Stainless Steel 76mm

Remus Mid-Pipe Upgrade for BMW 8 Series M850i xDrive G15 Coupe - OPF Vehicles

Unleash the V8 soundtrack of your BMW 8 Series M850i xDrive Coupé with this Remus non-resonated centre section. Purpose built for OPF-equipped 4.4 litre N63 twin turbo V8 models from 2018 onwards, this straight-through middle pipe replaces the factory silenced centre unit to deliver a harder-edged, motorsport-inspired tone with freer flow and reduced back pressure. If you are searching for an M850i mid-pipe, centre pipe replacement, OPF-back race section, stainless steel 76 mm centre tube or performance exhaust middle section for the G15, this is exactly what you need.

Crafted in Austria from high grade stainless steel with a shot blasted finish, the Remus centre section is a direct bolt-on that integrates perfectly with the OEM system. It is the ideal foundation for a complete OPF-back performance setup when paired with the Remus Sports Label rear silencer for the G15 M850i.

Key reasons to choose this Remus centre section

• Non-resonated straight-through design for a more assertive V8 note and race-bred character
