Remus Resonated Valved Cat-Back Exhaust System for BMW 1 Series M140i (F20/F21 LCI) 20152018 | Stainless Steel | EEC Approved | Fits Non-GPF/OPF | 102mm Tip Options | B58B30

Performance valve-controlled resonated catback for BMW M140i F20/F21 LCI

Give your B58-powered 1 Series the soundtrack and response it deserves. This premium Remus resonated catback delivers a deeper tone, sharper throttle feel and everyday refinement with factory-style valve control. Built from full stainless steel with a shot-blasted finish and engineered in Austria, it is type approved for road use and tailored precisely to the M140i F20/F21 LCI platform.

We run this system on our own M140i and our customers love it. With the valve closed it is calm and comfortable for commuting. Open it up and you get that unmistakable Remus character: rich, clean six-cylinder note, no harsh drone and real presence when you want it. Fitment is spot on, the quality is excellent and the look with the 102 mm finishers is spot on.
