Sport GPF [Mk4 Focus ST]

The mountune Sport GPF for the Mk4 Focus ST has been developed as an effective way to reduce exhaust back-pressure at the turbocharger, improving turbo response and releasing additional power and torque.

Incorporating a larger diameter 3” bore entry and exit with a high-flow GPF housed at its core, you can benefit from a substantial reduction in back-pressure and in-turn enhanced power and torque output across the entire rev-range, whilst still maintaining conformity to UK emissions requirements*.

The mountune Sport GPF is also supplied with an adaptor pipe which allow easy installation with the mountune GPF-back exhaust system.

Please Note: Revised engine calibration will be required for optimal performance.

Features:

  • 10PS / 10Nm peak power / torque increase
  • High-flow GPF core
  • 3” 304 stainless steel tube
  • Compatible with mountune GPF-back exhaust system.

Recommended to installed in conjunction with mountune Mk4 Focus ST GPF Back Exhaust and mountune Downpipe / Sports Cat.

WARNING:
This product has been designed and is intended for UK markets and complies with UK MOT tailpipe emissions regulations. Installation of this part on a vehicle that is driven on public roads outside the UK may violate other territories laws and regulations relating to emission requirements and motor vehicle safety standards.

*based on the current UK MOT emission testing requirements.

      Down pipe

      Great bit of kit, easy install using a car lift, Few stubborn bolts removing the old one but was sound with a bit of persuasion!

      Focus st m365

      This was fitted when in for the full m365 package, the quality of parts is superb. As for effectiveness I can’t say but less restrictions in the exhaust is no bad thing and the car now flies
