Anyone round off the nut on the passenger manifold lower bolt when trying to remove their stock mid pipe? This happened to me yesterday. I started by spraying all the nuts with liquid wrench and letting them sit for 6-10 mins before removing the nuts. The first three went like a breeze, but the forth one, not so much. So if this has happened to anyone else, how did you get the nut off? Did you us a nut/bolt extractor or did you back the stud out of the manifold and remove the nut after the stud was out of the manifold? Any info would help, thanks guys
