Cat Back Exhaust [Mk7 Fiesta ST]

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.

*Please contact us for warranty terms and conditions.

    Great upgrade

    Simple to fit and sounds ace. It's awkward to remove the stock exhaust past the rear axel but lining up and installing the mountune box it's very straightforward. The note becomes that little bit deeper but doesn't make a horrible noise day to to day on my MP215. Once it had bedded in the gurgles and pops began to appear naturally. Only gets better with time and it's looks great

    Best exhaust available

    I'm so glad I went with the mountune exhaust, instead of one of the cheaper brands. The quality is amazing and the sound is perfect. I'm also blown away with how quickly it was delivered. I live in sydney Australia and it took 6 days to get here. Very impressed. Can't wait to get the new large intercooler and m230 upgrade next :)
