If you are careful, the exhaust gaskets can be reused a number of times. You can gently open them back up a little with a large blade screwdriver, but be careful that you prise them open only a little way, and do it evenly.
You can also use a very small smear of high temp exhaust sealant on them. It's not something you need to do often, so resusing them a couple of times is no big deal.
And yes, they are very expensive for what they are!
