First on the market performance downpipes for the new 2018 Audi RS4 / RS5 with Porsche's twin-turbo 2.9 engine!

Compatible Vehicles:

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

*Available Options:

  • GESI Ultra High Output (UHO) 7830 high-flow metal core catalytic converters, rated 580-850hp each. EPA certified for use on OBD2 vehicles (1996 and newer) in the lower 49 States. 
  • OEM-style Heat Shielding with ceramic inner liner - the best way to reduce radiant heat up to 70%. Usual thermal wraps or coats not even close in effectiveness and durability to the Heat Shields. A must-have option for the modern temperature-sensitive turbo engines.

Main Features:

  • Significant power gain
  • Faster spool up and better throttle response
  • Increasing the life of the turbos 
  • Reducing underhood temperature
  • Adds a very nice tone to the exhaust

  • OEM-spec V-band flanges

Notes:

Removing factory catalytic converters will trigger a сheck engine light. We offer in-house tuning at Garage Auto Sports to provide maximum power/torque gains in addition to bypassing any fault codes/check engine lights.
