MK7 Fiesta ST Decat Downpipe - Cobra Exhaust.


If you're looking to build the ultimate power-driven Fiesta ST then you will need a decat downpipe. The Cobra Sport Decat Downpipe for the Fiesta ST MK7 creates an unrestricted flow of air from the engine to the exhaust system.

At stock, the Fiesta ST and all other cars come equipped with a Catalytic Converter downpipe, which filters out the harmful emissions produced by the engine, ensuring your car passes the UK emissions laws, allowing it to be road-legal. Despite this, the catalytic converter drastically restricts the flow of air from the engine. This restriction sapps power from the engine as it is unable to expel the gases quick enough.

Swapping the stock downpipe for the Cobra catless downpipe Fiesta ST creates a straight flow of air from the engine to the exhaust, allowing your engine to work to its maximum potential, putting no restrictions on how much power gains it can produce. If you plan to have the Fiesta ST Stage 2 Remap then you are required to swap out the downpipe.


  • Unrestricted airflow
  • Unlimited power potential
  • Constructed from Aircraft Grade 304 Stainless Steel
  • Lifetime warranty guaranteed.

The Fiesta ST180 catted downpipe is sold for off-road use only, and will not pass an MOT or police roadside checks. However, this exhaust is also available as a high-flow cat sports cat version, which will pass these checks.

Cobra Sport performance exhausts enhance the sound, looks and quality of your vehicle giving you the ultimate driving experience. Our sports exhausts range is fully guaranteed to give you assurance of our quality.

This Ford Fiesta ST catted DP performance exhaust is made in 3"/76.2mm bore pipework and fits from the stock turbo to the centre section, replacing the stock DP. The Fiesta ST downpipe gains power throughout the rev range due to its unrestricted flow.
