To remove the exhaust pipes from the engine, I used a couple of "wobble" extensions. Use 1/2" not 3/8"-ask me how I know. Be very careful too, because it's easy to round off the nuts at the angles you'll be working at. The real PITA you're probably going to have is the upper transmission bellhousing bolts attaching it to the engine. Those were very difficult to persuade out. If you have small hands it helps.
