Cat Back Exhaust

The mountune Mk7 Fiesta 1.0 Cat Back Exhaust reduces back-pressure and improves performance, whilst keeping cabin intrusion / boom to a minimum.

A Helmholtz chamber design is utilised in the rear silencer which helps to cancel out unwanted frequencies due to the way in which the exhaust gas waves are reflected. Utilising this system, despite being more complicated and expensive to manufacturer, ensures back-pressure remains low, providing the optimum in terms of performance, whilst removing as many of the unwanted frequencies / cabin boom as possible.

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

Due to the outlet position of the tailpipe trims, an aftermarket ST-style, or genuine Ford Fiesta ST lower diffuser section is required to ensure correct visual appearance.

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 racing flag logos
  • Limited lifetime warranty*
Note: If this item is fitted with the mountune Exhaust Isolator, we recommend using two isolators on the silencer only.
*Please contact us for warranty terms and conditions.

    Mountune cat back exhaust fiesta mk7.5 1.0

    So pleased with my new exhaust, it sounds so great on idle, but it doesn’t drone when driving at constant speed like motorways. A lovely deep rumble.. The tailpipe has a lovely finish and cleans up easily with a touch of metal polish, the build quality seems well made, customer service throughout the purchase was spot on!! Thank you

    1.0 Catback exhaust

    Absolutely great sound from the outside yet minimal cabin noise as described, perfect for anyone wanting for noise from their car yet a still peaceful drive from inside.
