Never ordered an F1 x pipe as they appear to impede flow, maybe there's a weak spot in those. That being said, a failure of one in MANY is not uncommon. This is the only failure I've heard of.
We have several customers out there with systems that see frequent track use and lots of heat cycling with no issues. My personal E92 has an IPE system with over 20K miles and a few track events with zero issues. Either way, the systems themselves are far from garbage or I wouldn't have one on my car.
