Anyone use these things? If you are familiar with the headers gaskets with the graphite inserts, the collector gaskets are the same way. I installed (or rather attempted to) their collector gaskets and found that they were waaay too fragile and fell apart. I give up on these things because the collectors leak worse now than they did before without any gaskets! My y-pipe needed more ummm.... convincing..... than old Earl was willing to give. Any recommendations on other brands since I just threw $20 down the tubes?
