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.
