Anyone on here have the version 2 forge? I found this clip on youtube, its on a CX-7 http://www.youtube.com/watch?v=KZLeguDlM70 I was wondering about this valve, does anyone know if it's still adjustable with different spring/shim combinations?
It is still adjustable. Saw a review on on another Mazda Speed forum. I like the sound of the ver 1 but I could understand people wanting a quieter version.
