Description

Upgrade the Audi S8 D5 4.0 TFSI V8 Saloon / Sedan - Long Wheel Base (2020+) 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.

Sound options

  • Resonated options keep cruising drone down and sound closer to a refined sports car.
  • Non-resonated (louder / race) options give the loudest, rawest note. Better for track days and weekend cars than daily commuting.

Choose your setup

  • Sound: the system type and sound level.
  • Tip Finish: the tailpipe trim.
  • Optional Downpipe: add a Milltek catted or catless downpipe built to fit this cat-back. Pick Cat-Back Only to skip it.

Cat-back systems: compare every part number
