BMW 240i (F22/F23 2 Series) Remus Resonated Valved Cat-Back Exhaust | 2x 102mm Stainless Tailpipes | 84mm System | Non-GPF/OPF | Deep Sound, Low Back Pressure | Handmade in Austria

Remus switchable cat-back system for BMW 240i F22 and F23 with resonator and twin 102 mm stainless outlets

Give your 2 Series B58 a serious upgrade from the catalyst back with Remus engineering. This Austrian crafted rear section combines a flap-controlled silencer and a resonator to deliver a bass-heavy tone under throttle with civilised manners on the motorway. The large 84 millimetre tubing reduces restriction for sharper response, while the straight cut 102 millimetre polished tips fill the rear apron beautifully. Built entirely from stainless steel with a shot-peened finish, it is a high quality performance exhaust for enthusiasts who want sound, style and durability in one package.

How it sounds and drives

With the valve shut you get a refined, bass rich note that keeps long journeys comfortable. Open the flap and the system delivers a more aggressive, track inspired soundtrack with crisp overrun character. The free flowing 84 millimetre layout reduces backpressure, helping throttle response feel cleaner and more immediate.

Tailpipe finish

Delivered with two stainless steel outlets, 102 millimetres in diameter, angled and straight cut to sit perfectly in the rear valance for a purposeful, factory-plus aesthetic.
