REDSTAR performance downpipes for the new 2018- Audi B9 RS4 / RS5 with Porsche twin-turbo 2.9 engine. Our downpipes utilize big bore design with smooth transitions for maximum flow efficiency. Long cones used to reduce the OEM 127mm turbo flanges to 89mm main diameter, which then goes down with second transition to 76mm lower 3-bolt flanges.

Compatible Vehicles:

  • 2018- Audi RS4 8W B9 2.9 TFSI
  • 2018- Audi RS5 F5 2.9 TFSI

  • Double-layer heatshielding is used to protect surrounding parts, wires, and hoses against radiant heat from the downpipes.
    Integrated thermal insulation reduces surface temperature up to 70%! What makes it an absolute winner, compared to usual thermal wrapping or ceramic coatings.
    It’s very important not just for safety reasons but also affects engine performance by reducing the underhood temperature. We highly recommend this option, especially for catted downpipes.
