Ford Focus RS Downpipe With GESI High Flow Catalytic Converter by Extreme Turbo Systems

Add more horsepower and torque to your Ecoboost Focus RS with an Extreme Turbo Systems Downpipe! We manufacturer the ONLY full 3.0" downpipe for the Focus RS in house using mandrel bent 304 stainless steel tubing for maximum airflow and durability. We designed our downpipe to eliminate the restriction in the factory downpipe by doing away with the restrictive vband connection and changing it to a slip fit 3.0" connection.

GESI High Output (HO-series) and Ultra High output (UHO-series) Universal Metal Core Catalytic Converters have been designed to provide a reliable solution to the most common converter problems experienced by our customers.


  • Direct fit to an Extreme Turbo Systems Catback
  • True 3.0" design for maximum flow
  • GESI UHO-Series Catalytic Converter - Rated for 850hp
  • EPA certified for use on OBD2 vehicles (catalytic converter)
  • Unique end-cap design locks substrate in (catalytic converter)
  • GESI proprietary precious metal loading tech (catalytic converter)
  • Capable of withstanding up to 1500 deg F
  • Ideal for forced induction applications, with no loss of HP


Other aftermarket 3.0" exhaust systems will work, but you will need to cut the restrictive vband connection off in order to connect our downpipe to your catback.

All engine modification components, except those that are exempt, have been designed specifically for off-highway application. Check your state and local laws before purchase.
