Hey guys, going to be installing my Megan exhaust stuff soon and not sure if I trust the gaskets that came with it. Plus, I need some gaskets to use on the cat and catback that I got used. The ones that came with the new downpipe and o2 elbow look like this:

and I'm not sure if I trust those after hearing some stories about the pack in gaskets blowing out. So I'm curious what online store carries a better quality gasket, so I can just get a whole kit of the good stuff and won't have to worry about them blowing out a few months down the road.
