Got some new exhaust gaskets and lock nuts form the dealer.

The old gaskets looked pretty good and I was tempted to reused them but they are such a PITA to get to I didn't want to risk a failure. I'm glad I did after getting them home I measured the thickness of the new versus the once used and the new ones were about .025" thicker. They are compressed or crushed as the nuts are tighten down, forming a seal. The .025" difference was not visible by eyeballing them.

The nuts were in pretty good shape too, but the locking tabs weren't working too good on a few of them and a couple were rounded a little. If one was to round off too much I'd probably have to remove the whole engine to get it off.

The part numbers seen in the pic are for a 2001, costs were $9 each for the gaskets and $1.50 each for the nuts.
