Milltek Non-Resonated Cat Back Race Exhaust System for BMW M140i F20 & F21 | LCI | Non OPF

Unleash the full acoustic potential of your BMW M140i (F20/F21 LCI) with this Milltek Sport Non-Resonated Cat-Back Race Exhaust System. Designed for non-OPF LCI models, this louder, non-resonated cat-back system removes the factory resonator for a more dramatic, uninhibited exhaust tone — perfect for track day use or drivers who want the maximum acoustic transformation from a cat-back upgrade.

A direct bolt-on replacement for the OEM cat-back section. Available in five tip finishes to suit your preference. Works with existing OEM downpipes and catalysts — no remapping required, though a Stage 2 tune will further unlock the M140i's performance. Manufactured from 304L stainless steel in the UK.
