Exhaust Whine Through Speakers when A/C is on
So I noticed this whining noise coming through my speakers that mimics the revs as they go up and down, and it only happens when the A/C is on. Anyone know if this can be eliminated? Its really annoying.

It likely isn't the exhaust "whining".
I have not experienced it with my 135, but I have had other turbo cars where the speakers picked up a whine from electromagnetic interference from the turbos spooling up (that would explain it corresponding to increases in RPM). Any metallic spinning body is going to create an EM field, so it is not uncommon for the speakers to pick it up.
