Recently purchased a set of headers from Pacesetter their longbody style for Samuai's. There is one particular tube on these headers that is the longest and has a split fit design. This tube is ratteling like crazy while driving my Samurai rattles worst around 3000-4000 rpms. I contacted Pacesetter they said to drive it for awhile and it will form a carbon seal. It's been awhile no carbon seal. I suppose I'm going to have to tact weld where the two pipes slip in to each other. Has anyone else experienced this issue or know anything about it?
