What's up guys!! I'm writing this in hopes that i can get some input. I was in the process of replacing my entire exhaust on my 02 ecotec and was unable to remove the nuts that bolt the catalytic converter pipe to the exhaust manifold. They would not budge and was wondering if there is anything that i can do to try and remove these without breaking the studs. Any kind of help or input would be greatly appreciated. Thank you .......
