Armytrix - 2017 Aud A4 2.0T

Also note that the B9 A4 has a S4 diffuser installed to make room for the quad tips.

In terms of sounds, it does add a nice depth to it and because it's on a video I can't really grasp how loud it really is. It does sound nice though but for the tag that Armytrix has attached to it, I would wait and see what an APR system sounds like.

I love the difference in sound it makes, too bad the sound with the valve opened is too loud for my neighborhood, doubt that even keep it at low RPM's will do anything much. Leaving home early in the morning its dead quiet.

One thing I don't like about these systems is they are too high pitched, deeper tone is what i prefer.

It does make a very noticeable difference but I'm not too sure if I like it... I agree with Alpha on this one and prefer a much deeper tone. This is too high pitched. I don't mind the raspiness at all and think it's a good quality of theirs but it could be much deeper.
