Remus Valved/Switchable Non-Resonated Cat-Back/Catback Exhaust for BMW 2 Series M240i 3.0 B58 (F22/F23) 2015-2018 - Straight-Through Sports Performance System, Twin Outlet - ECE Approved, Street Legal - Pre-OPF/No GPF

Remus performance switchable cat back for BMW M240i F22 F23 3.0 B58 2015 to 2018

Turn up the character of your turbocharged straight-six with this premium Remus sports system. Crafted from stainless steel with a shot-blasted finish and precision welds, it replaces everything from the catalytic converter backwards for a freer-flowing, straight-through layout. The factory flap motor is retained, so you keep full OEM drive mode control: subtle when closed, commanding and purposeful when open.

We’ve installed and run this system on customer M240i builds at MJ Modifications and the feedback has been outstanding. Fitment is spot on, the tone is deeper and more authentic, and throttle response feels crisper thanks to optimised gas flow. Built in Austria and EC type approved, it’s a road-legal upgrade for drivers who want proper quality and a serious soundtrack on pre-OPF cars.
