Personally I wouldn't recommend the 3.46 ratio with your MT. The ratios in the MT are short enough as is.
If you decide to go with the 3.46 ratio, keep in mind that it could impact the core charge.

Many of you may not know this, but Mfactory chose to use the smaller 3.46 final drive, not the correct large case pumpkin that is more expensive and harder to come by. If you have a MT, that is a 3.08 large case and should only replace it with the same large case 3.46 from the early 335i autos.
