You'll also need a good pry tool to get the old gaskets out. It won't even look like you have any but they're in there. I actually used a hawk blade box cutter so I could get in behind the gasket and pry it out. It took a while but I eventually got it. It's also important to use some anti seize on the threads when you're putting your new pipes on. You may also want to use some good lubricant on your threads and let them soak for a while before attempting to break the acorn nuts. I think there have been a number of people that have twisted off the bolts because the acorn nuts were frozen on there. Once you put your new pipes on then tightening them evenly and torqued to specs is critical. Ride for about 50 miles and torqued them again to make sure they haven't loosened up a little.
Glad to help. The hardest part of the whole job is getting the old gaskets out.
