Hi all,

was making a recording to pin point the annoying resonance i was getting with the Borla Axle Backs - turns out its at about 230hz.

whilst making the recording however i noticed i made a pretty strong case for how annoying the noise is coming from my transmission too

Rule of mustang transmissions . If they start being quiet worry , be very worried

Noise from axlebacks might be simply hangers need tightening, especially at that range. If it was higher it would be something else

Just by way of update

I just yanked and capped the sound tube and it has significantly reduced the whirring sound. Obviously a lot of it was intake sound then.
