Sounds like your installation for the pipe went wrong or you have a comound issue.
I'll certainly give it a go.

The pipe was installed by a mechanic but I was getting the same error before it was replaced which made me replace it. There was actually nothing wrong with the original pipe either - no cracks, damage etc.

Having said all this, the car is remapped so that might have a bearing on the situation although I do remember this code appearing before I got the remap. The hissing was also there from day 1, it just got louder after the remap.
