I found the exhuast leak on my car and it's located if u look from the top view behind the engine and were it starts to connect to the back of the engine. I was just wanting to know if anyone knows how much it would be to fix? It sounds so bad when I push on the gas, like a rock jumping up and down in the piping. Help me if u can.

 

i got a quote from a car shop here in panama city, florida for $126 for labor for the front and $116 for the rear...$35 for the gaskets.

 

At least one of your exhaust manifold studs has broken. Get them ALL replaced with new ones or the rest of the will eventually break. If they are broken out, you'll have to drill and tap them out (not fun). Get them replaced NOW before any more break. Have fun!
