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.
