alex... these studs ain't goin' nowhere, man. MAPP gas did not work. i'm halfway through drilling them out, but the uppermost one is impossible to get to. i have one side free - the other is the impossible one. i am going to cut through the pipe about 10" downstream of the flange, and then i can remove the exhaust. once i am done with the entire project i will bring the car to my friends' shop and have him weld it back together since he can weld stainless. it's just not worth me spending hours and hours on my back not getting anywhere!
