OEM+ Exhaust System - BMW M340i F30 Back Box Mod

Unlock the true sound of your BMW M340i with our OEM+ Exhaust System – a performance-focused back box modification designed to enhance exhaust tone while maintaining the factory look.

This OEM+ upgrade has had all the internal sound-dampening components removed from the original rear silencer, allowing your M340i’s turbocharged engine to deliver a deeper, more aggressive exhaust note without compromising everyday drivability.

By retaining the OEM back box casing & tailpipe design, this mod offers a stealthy appearance with a noticeable sound upgrade – perfect for enthusiasts who want increased volume & character while keeping things clean and OEM.

Fits: BMW M340i F30 2011-2019
