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.

These Fiesta performance exhausts are made in 2.5"/63.5mm pipework and fit from the catalytic converter section backwards (Cat-back) these parts replace the centre and rear sections.

This part has been designed to replicate the look of the Mk8 Fiesta ST when matched with the replacement rear diffusers (available seperately).

The resonated exhaust option includes the centre silencer and has a subtle but sporty tone. This exhaust however, is also available as a non-resonated version which is a louder option, as it excludes the centre silencer and therefore, has a sportier exhaust note. 

All relevant fittings and gaskets are supplied.

Following on from the success of the top selling Cobra Sport Exhaust conversion range for the Mk7 Fiesta, the Cobra Sport team were keen to add to their offering for the Mk8 ST-Line by adding a unique ST style twin tailpipe conversion. The Cobra Sport team have worked their magic on the EcoBoost Fiesta by creating an highly improved and refined sound track matched with the sporty style of the twin tips to give an Mk8 ST look.

The cat backs are available with a resonated or non resonated section allowing those looking for some extra drama to opt for louder non resonated exhaust and those seeking a more subtle enhancement to go with the resonated option. The stand OE exhaust system recorded 74.9dB on the static 4,000rpm track test, the resonated Cobra Sport exhaust option increased sound levels by +8% to record 81.5dB. The non resonated cat back option goes a stage further producing a much sportier dynamic sound track when under full acceleration.

Matt Thomas, Sales Manager at Cobra Sport says "Our existing 1.0 litre EcoBoost exhaust range has been a strong seller since the cars launch in 2018. To cater for market demand, we've expanded the range to include a Mk8 Fiesta ST style conversion to give ST-Line vehicles the sportier twin tip look. When matched with the lower diffuser and trip panels from the ST model (available separately directly from Ford), the twin tailpipe look gives a far more aggressive look to the rear of the car and matched with the signature Cobra Sport soundtrack, completely transforms the 1 litre model".

As with all Cobra exhaust developments, power increases, sound improvements and manufacturing quality are top of the priority list during development. Superior TIG welding techniques during the manufacturing process set the Cobra Sport exhausts apart from the competition. The levels of quality achieved enables us to offer a lifetime guarantee on all exhaust systems which provides the ultimate peace of mind for the customer.
