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 the UK, mountune's 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.

Features:

• High-flow cat-back exhaust design improves performance
• EC Approved Resonated System 
• Engineered Helmholtz resonator for a less intrusive, performance sound
• High quality 304L grade stainless construction with CNC welds
• Staggered, twin-tailpipe trims with laser-etched mountune logo
  

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