I have had NOTHING but issues with MAC headers...their multi flange design is horrible, they move when they get hot

Anybody else had this problem? I was planning on getting these sometime, but not if everyone has trouble with them. And not for awhile anyways, I just got my o/r h-pipe a month ago. Not going to pay another $200.00 for a shorty h-pipe already.

hell, I have seen MAC's coaying get scraped off by a fingernail, a new strut tower brace not line up with a car that was never hit, and rusted out mufflers that were less than a year old
