Fast Intentions exhaust is here! (continued)

kfull

I've also noticed a faint hissing sound when idling since having my new x pipe installed. I can hear it in the cabin and outside the car mainly if I put my head right next to the right rear tire. 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.

That's normal buddy and I have the same setup with non resd T.P, look at my signature, the hiss sound is normal its the engine hissing as far as what I have read but I love it makes it sound like a BOV

Yea I know about the VQ hiss on deceleration or after revving the engine, but this hiss is just during idling when the car is stopped, that's the only reason it concerned me.
