Remus Rear Silencer Left/Right with Integrated valves using the OE valve control system with 4 tail pipes Ø 84 mm straight, carbon insert - 3 Series G20/G21 320i 135 kW B48B20B 2018-

Valved performance rear section for BMW 3 Series G20 G21 320i 2018 onward

Unlock a deeper, sportier soundtrack and sharper response with this Remus valved rear section. Designed for the BMW 3 Series 320i G20 saloon and G21 Touring with the 2.0 B48 engine, it delivers a purposeful tone when the flap is open and a refined, civilised note when closed. Quad 84 mm straight cut outlets with carbon fibre inserts complete the look for a premium, motorsport inspired finish.

We have fitted this system at MJ Modifications and customers love the sound quality, the build, and the factory style valve integration. It is a brilliant upgrade for enthusiasts who want a high quality exhaust tone without drone on the motorway.

Why choose this upgrade

• Valved sports exhaust keeps comfort in normal driving and wakes up with a rich, aggressive note under load
• Austrian hand built construction with a shot blasted finish and 100 percent stainless steel for durability
• Reduced back pressure for a real performance uplift and improved throttle response
• Lightweight design with excellent fit and alignment to the factory mounting points
• Factory style valve control retained. Plug in the original actuator so drive modes work as intended
• Eye catching quad 84 mm tips with carbon inserts for an OEM plus appearance

Compatibility

• BMW 3 Series G20 saloon and G21 Touring
• 320i, 135 kW, B48B20B, 2018 onward
