option:

Non Resonated TP79

Requires mandatory ECU reflash

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 Focus Mk4 ST cat back performance exhaust is made in 3"/76.2mm pipework and fits from the Catalyst section backwards (Cat-back) replacing the GPF, centre and rear sections.

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

IMPORTANT: this exhaust removes the GPF filter and will require engine tuning at time of fitment to cancel the EML light.

Fitment to GPF equipped models is for motorsport and off road use only.

Press Release
