Exhaust Isolator [Mk7/Mk8 Fiesta ST]

The mountune uprated Exhaust Isolator helps ensure accurate alignment, particularly when attempting to DIY install the mountune cat-back exhaust for either the Mk7 or Mk8 Fiesta ST, without proper access to the underside of the vehicle.

The exhaust isolator features a higher shore hardness compared to the OE isolators, which helps to reduce movement of the rear resonator, whilst transmitting minimal additional NVH into the cabin of the car.


  • Allows for easier DIY installation of cat-back exhaust
  • Minimises rear resonator movement
  • Uprated shore hardness
  • Minimal increase to NVH
  • Sized to fit and complement the mountunemk7 cat-back exhaust hanger
  • Sized to fit and complement the mountune mk8 GPF-back exhaust hanger

Please note: Isolator sold individually. We suggest purchasing two isolators, to be used with the silencer only.

Ordered this item in preparation for use with the catback exhaust which I intend ordering when it is eventually back in stock and available to purchase. Item seem to be to the usual Mountune high quality and feel confident they will perform very well.

Quick delivery, hoot replacement for standard isolator and works perfect with sports cat back.
