The mountune Downpipe / Sports Cat has been engineered for the mk3 Focus ST to reduce exhaust back-pressure at the turbocharger, allowing faster response and additional power. The 3" pipe includes a large diameter 5” motorsport-type, 200 cell count metal substrate honeycomb catalyst, to ensure effective, ultra high flow performance in extreme environments.

We recommend this product is fitted with mountune cat back exhaust.

Please note: Revised engine calibration will be required for optimal performance and your vehicle may emit the EML without it (our m300HT calibration will support this).

This product includes a fixed labour charge for installation at mountune HQ in Hutton, Essex. This is a comprehensive drive in, drive out service, where you can make use of our comfortable and spacious customer waiting area while the work is being carried out.

Fitting time: 2 hrs

Please note: the price shown for this product includes installation at mountune HQ only, and is not transferrable to any other dealer or installer.

Please specify your preferred installation date in the 'notes' section when checking-out; our workshop team will then contact you to confirm this date. If we can't accommodate your preferred choice, the team will discuss other available dates.

Whilst this product will pass current UK MOT tailpipe emissions regulations, it utilises a high-quality motorsport catalyst, which is therefore designated for off-road use only in the UK.
