Milltek Exhaust GPF Back System for BMW F40 M135i.


This Milltek Sport BMW M135i exhaust is the perfect upgrade for anyone looking to improve the sound and aesthetics of their new M135i xDrive. Designed to directly replace the stock system for ease of fitting. This Milltek Sport GPF Back System will transform the exhaust tone of your hot hatch. Available in multiple configurations enabling you to choose to increase the volume of their exhaust and alter the aggressive tone to suit your mood.

Constructed from 304L Grade stainless steel, this exhaust system is designed to handle to toughest of conditions. The stock exhaust on the new BMW M135i xDrive models is a restrictive pipe, that prevents the engine from working to its optimum potential. Installing this exhaust will not only improve how the exhaust sounds but it will also improve the engine's performance output to the front and rear wheels. Replacing the restrictive pipework with Milltek's 3" smooth pipework allows the gases to flow more easily from the engine, preventing backpressure. This also improves the fuel consumption of the car as the engine is having to work less to produce the same power.

Key Features:

  • Enhanced aesthetics.
  • Amplified exhaust tone.
  • Constructed from 304L grade stainless steel.
  • Multiple configurations to control the volume and aggressiveness of sound.
