I tried doing some research but couldnt find anything not related to PSU noise, I was wondering how I can get my A350 to sound more like a A350T From what im reading its the stepper motors? Are those swapable?

There was a replacement kit of the linearmodules which are driven by silent steppers.  
Unfortunately i cant find this kit to buy, maybe reaching out to support would offer you a replacement set.

Note, it was communicated that you have to exchange all 5 modules to silent steppers (never tested if its really needed).  
With the new linear modules the leads of x and y would change from 8mm to 20mm, z would stay at 8mm leads.

New linear modules are marked with lead:

If yours are marked like this, you already have the silent ones.  
If not, you have the older, noisier ones.

Have to upgrade all 5. Can’t mix and match old and new.

They sent out 50% off coupons to all Kickstarter, and I believe, original (early?) owners. There was supposed to be no expiration date on them. You can contact support and inquire.
