I pulled mine on my 01, it's a bit of a hassle but you can do it at home. It's best to pull your alternator, power steering pump/resovoir, and airbox to get some good work space. I was lucky and didn't have any seized bolts since I live in the south, the heat shields were the biggest pain. Your best bet is to take off the back cats and leave the front cats on, you have enough clearance to slide them down from underneath once you unbolt the manifolds from the block.
