I'm so glad someone posted this, I just installed my bark HFC's this week and I got the hiss and I was worried I had a leak cause everything was darn tight up underneath. I didn't really understand how a leak would even create the hiss but I was worried something might have been wrong.
Oh well, maybe some people will be fooled into thinking it's a real quiet blow off valve or something. Z's are exploding with personality already, a hissing exhaust? Just one more unique thing to love about my car. As long as nothing is wrong, I'm happy with it.
