Is there a way I can tell an 06 from an 05 piston if I take off the y pipe? I know I can tell once I get the cylinder off by looking at the shape of the hole the piston pin goes through. I just do not really want to take of the cylinder if I do not have to. I think I remember something about the size of the ring. I have a few 05's laying around but no 06 to compare it to.
