I'm still out here changing things up every now and then. The other day I put in the Perrin intake hose, obviously in red for the big hp gains.
I really like the deletion of the sound tube. The cabin is definitely quieter, but it also to me sounds lower and less artificial. I tossed a new H&N filter in too while I was in there. I'm not sure that there's any performance increase, but there's obviously nothing much noticeable outside of the sound.
The only thing is the clearance between the tube and the belt is tight. I've kept an eye on it after a couple short drives, and there doesn't appear to be any problems or shifting, but it seems unnecessarily close.
