To get out stubborn exhaust hardware you need A LOT of heat. You have to get the parts up to dull cherry red and you can only do that with an acetelyne welding torch. As soon as you get the stud red you lock your vise grips on as tight as you can and it should turn although it may take the threads out with it! If you just can't get a grip on it you could weld a nut to the stud (oversize if you have to, it doesn't have to thread on) and use a wrench once you heat it up. As when using a torch on the motor take precautions not to damage anything with the heat like hoses and wires. STAY AWAY FROM ANY FUEL LINES. Remove them if you have to and have someone stand by with a fire extiguisher. When replacing use Never-Seize on all of the hardware.
