Resonating- thought it was from the exhaust but maybe not...

Have had this for a few months now, only under load (ie accelerating, not cruise)

It's absolutely driving me mad.

The garage that fitted my cup suspension thought it was something rubbing the exhaust.

Took it to PipeWerx (great guys, if you're in the NW they're one of the best) but they couldn't find anything- no witness marks or other signs of rubbing.

Anyway... completely by accident I turned the a/c off, and it *seems* to have reduced the noise.

Are there any documented cases of a/c compressors coming loose?

Thanks :smile:
