I have been searching the internet and i think i might have an exhaust leak somewhere. I only hear the ticking/hissing noise when i first start up the car for a few min. After the car warms up you can only hear it when you step on the gas a little when you want to speed up. The sound is coming from the passenger side like its behind the glove box or under it. I'm trying to look and see if its the intake manifold that's cracked or something but i don't know exactly what it looks like lol, I'm still fairly new to how cars work and stuff. Let me know what you guys think. Pictures of what the whole exhaust system consists of would be great. I would hate to pay 100 dollars just to find out its a loose bolt or a small crack in the flex pipe. Thanks.
