Mustang GT pulley has the squeaks

[nytebyte]

One of the pulleys on the girlfriend's GT is squeaking on startup.
It only does it for less than 2 min, then gets quiet again.

Assuming I can find out which pulley it is, I'd like to replace it since that kind of squeaking noise in unbecoming for a car like that.

Should I just replace it with another stock pulley or are there better pulleys out there, kind of like Billetflow has for our Cobra's?

Just replace it with a stocker or aftermarket part available from most autoparts store. Don't be surprised if it is the belt.

If you are really ambitious, you could just replace the bearing on the suspect pulley.

Just did this on mine, either its the Idle pulley, tensionor pulley, or a bad tensionor. I replaced all three for about $50 and it sounds great.
