All of these "fitment" issues are self installs. I installed these on mine and yes they drift to the sides if you just bolt them on. You have to loosen the catback pipe and adjust it until you get it right. I had another guy say the same thing that all of these other ppl are saying and I told him to do this and 30 min later he had them perfect on his car. You cant just throw somethin on your car as fast as you can and expect it to fit right. Take a little time to make it perfect and they will be fine.
