What's involved
What this repair actually is.
The resonator is a secondary silencer in the middle of the exhaust that tunes out specific droning frequencies the muffler alone cannot catch. When it rusts through, the car develops a raspy tone or a highway drone; we replace it with a direct-fit or welded-in unit and new hardware.
Symptoms
How you can tell.
- Droning sound at highway speed
- Raspy exhaust tone that was not there before
- Visible rust holes on the mid-pipe canister
- Louder exhaust but muffler looks fine
If you delay
A leaking resonator gets louder over time and the leak can spread into the surrounding pipe.
