Description
The mountune uprated Exhaust Isolator helps ensure accurate alignment, particularly when attempting to DIY install the mountune cat-back exhaust for either the Mk7, Mk8 Fiesta ST or Puma 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.
Features:
- 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 mountune mk7 cat-back exhaust hanger
- Sized to fit and complement the mountune mk8 GPF-back exhaust hanger
- Sized to fit and complement the mountune Puma ST GPF-back exhaust hanger
Please note: Isolator sold individually. We suggest purchasing two isolators, to be used with the silencer only.
