Milltek provide a range of large bore down pipe options for the Focus ST mk3 250.

We recommend ALL downpipe installs be accompanied by a re-map of your ECU as well on install.

We offer an ECE approved high quality hi flow HJS catted version, a Milltek catted version with high flow 200 CEL cat, and a motorsport only DECAT downpipe.

A high flow down pipe allows more efficient expelling of exhaust gasses and better turbo efficiency, adding up to more power and responsiveness when combined with a good remap.

FITMENT: All Petrol Focus mk3 ST 250 models including estate.

Connectivity:
HJS high flow to OE or Milltek cat
Milltek 200 CEL high flow cat to Milltek catback ONLY  (so not estate)

DECAT downpipe to OE or Milltek cat.
