Overview

Upgrade the Subaru Impreza STi & WRX STI Saloon / Sedan (2014-2021) with a Milltek Sport cat-back exhaust. Milltek builds each system around the car it fits: mandrel-bent T304L stainless pipework, a larger bore than stock for freer flow, and a tuned sound you choose, from quiet and refined to loud and uncorked.

Choose your setup

  • Sound: the system type and sound level.
  • Tip Finish: the tailpipe trim.

Cat-back systems: compare every part number
