T-4 or HMF for utility?

[dirtyboy88]

Which one has the most power increase, i want a T-4 but i also like the HMF , which one will sound good but not too loud.

For power...they are going to be pretty close. As far as noise goes, I believe the T-4 has a quiet core, so if you want some good sound I would go with the HMF:)
