I just got my stage 2 kit installed on my 13 frs. Now after about 5 minutes it starts making a horrible knocking noise. Almost like a tractor. Has anyone else had this issue or know what it may be? Here's the link to the original post with video of the sound. Watch the second video so you can hear it transition from normal to the loud knocking.
