Milltek Non-Resonated Cat Back Road Exhaust System for BMW M135i F20 | F21 (Non xDrive)

Sharpen the soundtrack of your BMW M135i (F20/F21) with this Milltek Sport Non-Resonated Cat-Back Road Exhaust System. Removing the factory resonator gives this system a louder, more characterful tone that brings out the best of the turbocharged six-cylinder. Available in three tip finishes and designed as a bolt-on fitment, this system is the ideal first performance exhaust upgrade for the F20/F21 M135i.

Road-friendly in character but with noticeably more sound presence than the OEM system, this cat-back is well suited to daily driving as well as spirited use. No ECU remapping is required. Manufactured from 304L stainless steel at Milltek Sport's UK factory.
