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.

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.

EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.

Following on from the success of the top selling Cobra Sport Exhaust range for the Mk7 Fiesta EcoBoost, the Cobra Sport team were keen to take delivery of the Mk8 ST-Line to add the same sound and power upgrade to the punchy 1 litre EcoBoost engine. The Cobra Sport team have worked their magic on the new Fiesta creating a highly improved refined sound track whilst also opening incredible tuning possibilities.

Cobra Sport have catered for all sound tastes and tuning requirements for the Mk8 by creating a range of exhaust systems to fit from the Catalytic Converter backwards along with the option to upgrade the turbo downpipe to either a de-cat or high flow sports catalyst downpipe. 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 "We've been really impressed with the new Fiesta releases and the 1.0 litre EcoBoost engine has a great mix of performance and efficiency. The 2.5"pipework utilised by the Cobra Exhausts completely changes the dynamic of the car offering an impressive improvement in sound particularly when put under load giving the car a really sporty edge. Our tuning partners had great success with the Mk7 EcoBoost Fiesta releasing packages easily upgrading the power to 175bhp with the help of the Cobra Sport exhausts and we expect similarly impressive results with the Mk8."

The Cobra Sport Mk8 Fiesta ST-Line exhausts are finished with choice of single tip 4" (101.6mm) highly polished stainless steel or ceramic black slash cut tailpipes engraved with the Cobra Sport logo.

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.
