Cat Back Exhaust

This part does not affect the base vehicle warranty.

The mountune Cat Back Exhaust for mk7 Fiesta ST reduces back-pressure and improves performance, whilst keeping cabin intrusion / boom to a minimum.

Designed and developed in-house by mountune's engineering team, the cat back exhaust utilises a Helmholtz chamber design in the rear silencer. This helps cancel out unwanted frequencies due to the way in which the exhaust gas waves are reflected. Despite being more complicated and therefore expensive to manufacture, this design ensures back-pressures remains low, providing the optimum in terms of performance, whilst removing as many of the unwanted frequencies and cabin boom as possible.

The staggered tail-pipe trim adds to the occasion and both trims feature laser-etched mountune logos.

As a mountune Performance product, this is also the only cat back exhaust available for your mk7 Fiesta ST that will not affect the base vehicle warranty, and comes with a limited lifetime warranty* against manufacturing defects.

Features:

  • High-flow cat-back exhaust design improves performance
  • Engineered Helmholtz resonator for a less intrusive, performance sound
  • High quality stainless construction with CNC welds
  • Staggered, twin-tailpipe trims with laser-etched mountune logo
  • Does not affect base vehicle warranty
  • Limited lifetime warranty

Please note: If this product is fitted with mountune Exhaust Isolator, we recommend using two isolators on the silencer only.

Compatible with all 3-door models globally and EU-only 5-door models. Customers in the USA please note there is a 5-door specific version, available at www.mountuneusa.com.

    Great sounding exhaust

    Had it fitted professionally and it's a massive improvement over stock, not too intrusive but can be improved by fitting the symposer delete

    Mountune Cat Back exhaust

    This exhaust is ace, comes with new bolts for the Cat to exhaust as the old bolts often snap so that helped haha! Sounds wicked, makes the car sound 10x better, would recommend to anyone thinking of getting a new exhaust

    Well 'appy!

    Really delighted with this exhaust not only because of the extra throb imparted to the engine note, but it also looks so much better than the OEM offering on the car. Be prepared to spend extra money upgrading the mounts however, as Ford's stock offerings suddenly turn into elastic bands - they just aren't up to the job as I quickly discovered a few days after having the heavier exhaust supplied and fitted by my local dealership (a complete set from Powerflex immediately solved that little difficulty). I've also taken a leaf out of Mountune enthusiast Adam Rainey's book and coated the cat back's tips with a detailing product designed to repel moisture and mucky deposits on painted and bare metal surfaces (Adam’s VLOG is on YouTube): a quick rub with a microfibre cloth and the tips look like new once again.
