Technical Data

This Fiesta ST performance exhaust is made in 3″/76.2mm pipework and fits from the turbo backwards (Turbo back system) these parts replace the front pipe, standard catalyst, centre and rear sections.

This sports exhaust is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks. This exhaust is also available as a high flow sports catalyst version, which will pass these checks.

This non-resonated exhaust makes the system louder as it excludes the centre silencer and therefore, has a sportier exhaust note. This exhaust is also available as a resonated version (including centre silencer) which is a quieter option.

All relevant fittings and gaskets are supplied. (Except turbo gasket).

Please Note:- Some of the fitted exhaust images may show alternative parts.


The team at Cobra Sport couldn’t wait to get their hands on the new Ford Fiesta ST and straight from the showroom this car was delivered to us for development of the exhaust. This car is surely set to be one of the best hot hatches ever to be sold and would definitely benefit from the added excitement which a Cobra Sport exhaust can deliver.

The system benefits from all of the usual Cobra Sport refinements with mandrel bent, TIG welded, grade 304 stainless steel used throughout the systems as standard. You can be assured of only the best quality in a Cobra Sport system. Matt Thomas, Sales Manager at Cobra Sport says “The new ST system has provided us with some exciting results, independent testing has revealed that the 3” Turbo back upgrade produces an additional 13bhp from the standard system with a 10% increase in torque.

A substantial weight saving can also be achieved with the 3” cat back system providing a whopping 17.2% decrease in weight from the Original Equipment version. Overall the Cobra Sport system makes a great car even better”. The styling of the system is finished off with either a subtle ‘OE look’ twin 3” slash-cut tailpipe or for something a little different there is a single 4” outward rolled option on offer. Both tailpipes come in a highly polished 304 stainless steel finish.
