So I took the car out again yesterday to see if it was just the excitement of having all the new parts installed that made me think it was better, or if it actually was. Well, I can confirm that it is for sure better. The ride is better, NVH has decreased, and the car is just a pleasure to drive. A conversation can be easily had, there is no drone, and even the gear whine seems to have backed off a little (maybe because of the aluminum drive shaft). You can now hear the M90 start to spool up much sooner where as before the changes you had to be hard on the loud pedal to hear the blower over the exhaust.
