REMUS Axle-Back Sports Muffler for BMW F20 F21 F22 F23 B58 3.0T - PN 089016 1500

Transform the sound and character of your 3.0 TwinPower Turbo with this REMUS valve-controlled rear section. Crafted from premium stainless steel with a shot-blasted finish, this performance rear box delivers a richer tone, sharper throttle response feel and reduced back pressure while keeping day-to-day refinement thanks to the factory-style flap control. EC approved for road use and built in Austria, it is the go-to sound upgrade for the B58-powered 1 Series and 2 Series.

We have installed this system on our own demonstrator and many customer cars. Feedback is consistently excellent on build quality, fit, finish and the addictive soundtrack when the valve opens. Closed-valve operation remains civil for commuting and motorway cruising.

Real-world results

Owners love the deeper start-up, richer mid-range tone and the way the flap opens for a more spirited sound on throttle. With the valve shut it remains neighbour friendly and comfortable on long journeys.
