Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Raise the game on your ST250 Mk3

Unlock sharper response, more drama and a cleaner look with this Cobra Sport stainless steel system for the Focus ST250 Mk3 2.0 EcoBoost. Built in 3 inch (76.2 mm) T304 pipework from the turbine outlet to the tailpipes, this comprehensive downpipe-back upgrade replaces the OE front section, factory catalytic converter, centre section and rear assembly for a true transformation in sound, performance and weight reduction.

Why owners choose this system

  • Proven gains: independent testing on the rear-half setup lifted power to 261.5 bhp with torque rising from 254 lb ft to 275 lb ft.
  • With the full non-silenced system and de-cat, results showed approximately +8.4 percent power and +2.4 percent torque, taking output to 274.7 bhp and 294.9 lb ft.
  • Weight saving: around 22.5 percent lighter than stock, helping the ST feel keener on the road and track.
  • Precision 3 inch free-flow pipework for improved throttle response and a richer soundtrack.
  • Tailpipe choice to suit your build: twin 4 inch inward rolled slash cut or a 4.5 x 3 inch oval slash cut.
  • Finishes: highly polished T304 stainless tips, plus a stealthy Blackout ceramic option for the 4 inch rolled style.
  • All clamps and hardware included for a straightforward install, excluding the turbo outlet gasket.
  • Fully guaranteed by Cobra Sport for added peace of mind.

Choose your sound

  • Resonated centre section: refined on a cruise with a purposeful note when you lean on it.
  • Non-resonated centre section: louder, more character and extra turbo presence inside and out.

Configuration options

  • De-cat downpipe: for track and off-road use only worldwide. Not for road use.
  • Sports catalyst: replaces the OE emissions device and is not EC homologated. This may not meet current road-going emissions rules in your region.

What you get

Complete downpipe-back assembly in 3 inch T304 stainless steel with your chosen centre section and tailpipe style, plus all required fittings and gaskets, except the turbo gasket.
