I had these before I went for my Tial BOV and with inlets, they were insanely loud... nice woosh sound. I really loved the sound with inlets... it sounded MEAN.

You could also go the BOV route as well... but the proven BOV is Tial and it's extremely quiet compared to the turbosmart.
Interesting even after checking out the site I didn't realize they were variable. Why did you go to Tial in the end then?
