Hey wanted a few overall opinions as to which is best for a 2006 GT. i know the X has a raspy note butim running an off road H now and it just sounds a bit tin like. I have run an X on older mustangs and not had that issue. My set would be an off road x and GTB axle back if i swap the H for the X. Thoughts??
...But I like the pro-chamber
