I just r&r'd my exhaust studs. I used penetrant first 50/50 ATF/acetone which freed up over 1/2 of them and then heat/oxy acet. I double nutted and working carefully tighten and loosen multiple times. In the end I had to use heat on just one stud. If you get to that point ensure that the valve is closed where you use heat on the aluminum. In the end I did not break a stud and replaced all.
