I set aside half the day to get under the car and put in my BAT y-pipe thats been sitting in my room for 2 weeks. Im steadily working, finally get the front banks nuts off, when I come to the rear bank nuts and post-cat nuts. I LIBERALLY spray them all with PB blaster, and wait 20 minutes. As I start to work on the rear bank nuts I find that theyre almost entirely rounded. Crescent wrench, vise grips, nothing did the job. Question 1 - How do I go about removing the nuts? (btw they arent seized on). Then i go back to the post-cat nuts (where the two flanges come together). The nuts and bolts are both seized horrendously. Looks like theyre almost welded to the flange (& inside the flange) its so bad. Question 2 - How can I separate the two flanges, while keeping the inside surface to the rear flange smooth (so a new gasket will seal properly), and how do I get the bolts out cause I need holes to be there for the new bolts supplied by BAT?
Im definitely taking it to an exhaust shop tomorrow, cause itll probably be 10x faster and less exasperating for me. Just need any input or suggestions.
