I have 4.44's in my 99 Outback 2.5 DOHC and at 75MPH tach is at 3000 RPM, and still relatively quiet, so I dont see how in a 3.3 it would make any noticeable noise. Everyone who has the 4.44's swears by them. Im currently waiting for svxfiles to find me a nice low mileage one to put in my 97 ebony.
