Remus BMW F22 & F23 M240i Cat Back Exhaust System

Transform the driving experience of your BMW M240i with the Remus Cat Back Exhaust System – a premium upgrade crafted for enhanced performance, sound, and aesthetics. Handmade in Austria using high-grade stainless steel, this full cat-back system includes a resonated or non-resonated midpipe and rear silencer, engineered to deliver reduced back pressure, sharper throttle response, and improved low- to mid-range torque, all while maintaining top-end power.

Known for its refined tone, the Remus system lets the B58 engine deliver a deeper, more aggressive exhaust note, making it sound as good as it performs.
