Trying to take off the mid-pipe/cat section of the exhaust. Just above the O2 sensor there is a support bracket on the pipe that is preventing me from sliding the pipe aft and removing it. When I slide it aft the bracket hits a nut that connects the suspension (link arm?) to the frame. I don't have enough room to twist the pipe to clear that nut. I could remove that nut (suspension) to allow me slide the pipe back. Anybody have a better technique?
