I got a 97 Ceica GT that hisses when it's cold but when it gets warm it stops. It sounds like it's coming from under the car somewhere. I'm thinking it's a leak from the exhaust pipe but if it was then it would've been hissing still even if it was warm right?

Yes I'm sure. I listened carefully all around my car and I can hear it mostly when I'm at the back right wheel by the exhaust pipe. I can also hear it when I'm in the car idling.

I get the same thing but its definitely from my intake. The hissing is really noticeable on startup.

However, it could also be a small exhaust leak in your pipe somewhere. The metal pipes expand when they heat up and this could plug a very small exhaust leak and cause the hissing to stop.


Yea. I was thinking that too.
