I know exactly what you are talking about.
I had an Akrapovic for a month. Was great.
Got Motordyne ART pipes . And it was the worst thing ever.. 6 days later i sold the whole setup.
Apparently some exhausts dont pair well with test pipes or whatever.
Its not hiss what people claim, Its the disgusting rattle that sounds like you have drilled a hole in your exhaust.
