HFC Failure, ever have it happen?

...all leading to failure.

On a side note, Berk posted in a different thread that they use Magnaflow cores and suggests that these are higher quality cores than those in other HFC options. Is it just me, or is Magnaflow more often associated with inexpensive products and lower quality? I don't think top-of-the-line when I hear about Magnaflow anything.
