Remus Racing Rear Section Performance Axle-Back Exhaust for BMW X3M & X3M Competition (F97 S58, 2019+, OPF/GPF) - Valved Flap-Controlled Back Box / Rear Muffler / Rear Silencer, Stainless Steel, Optional Carbon Fibre Tips - Bolt-On Direct Fit

Remus Performance Rear Section for BMW X3M F97 S58 GPF Models

Transform the character of your X3M with the Remus performance rear silencer assembly. This valve-controlled rear box replaces the factory back section to deliver a deeper, harder-edged soundtrack and a motorsport look while retaining day-to-day refinement. Built for petrol particulate filter vehicles, it plugs straight into the original actuator motors so you keep your driving mode sound control exactly as BMW intended.

Handcrafted in Austria from premium stainless steel with a shot-blasted finish, this X3M rear exhaust is engineered for high flow, precise fitment and long-term durability. It is a direct replacement for the OE rear silencer on F97 S58 models, with no cutting required and perfect tip alignment.

Highlights

• Valve-operated sound control that is tame when cruising and fierce when you want it
• Low back pressure layout for improved gas flow and performance potential
• Lightweight construction with excellent build quality and a premium finish
• Uses OE valve actuators and electronics for seamless integration
• Stainless steel, shot-blasted surface, handmade in Austria
• 24 month Remus warranty for peace of mind
