Switchable Sports Back Box for BMW 440i xDrive F32 F36 LCI 2015 to 2018 with 2 x 84 mm Tips

Give your B58-powered 4 Series the soundtrack and presence it deserves. This premium rear section from Remus replaces the factory back box with a valve-controlled, low restriction unit that works seamlessly with your car’s original electronics. Open the valves for a hard-edged, motorsport tone. Close them for a refined, deep note on the commute. Built from high grade stainless steel with a shot-blasted finish and crafted in Austria, it delivers a genuine upgrade in quality, flow and durability with European type approval for road use.

We run Remus systems on our own cars at MJ Modifications and our customers consistently rate the fit, finish and sound. If you want a switchable sports exhaust that keeps daily civility yet comes alive under throttle, this rear section is the one to choose.
