It isn't a constant hiss, it's more like a short hiss at random intervals maybe every half second to a second. It's not very loud either, I really have to listen to even notice it. Is a hiss like that more common with a non resonated x pipe? I know where the x pipe is welded together it has the cross over hole so I was hoping its just air going across that hole. I hope it's not a leak. I had the shop use the existing gaskets like Tony said.
