Just In Case
Start by reviewing the appropriate section of your service manual, the one entitled, _"Removing the Exhaust." _Among other things, it'll point out exactly what you need to remove, and in what order, along with a list of tools you'll need to do the removing. The last one is kind of a biggie. If the job requires a 13 mm swivel-joint socket and you don't have one, it's not much of a problem. They're common as dirt and not too expensive, so acquiring one shouldn't present any particular problems. On the other hand, finding out halfway through the project that a particular bolt isn't coming off without the help of a torch, which will work, but no doubt create other issues, or that missing socket, it's another story. Trust me on this; if that's the case then every shop that carries 13 mm swivel-joint sockets will be closed, out of stock or 100 miles away, as they say, forewarned is forearmed.
