Thread: Exhaust leak

So i have an exhaust leak somewhere but i cant find it. I can only hear it when i step on the gas and will increase as i step on it harder. I think this causing me to have a lean code on bank one. A lot of people say that its the header gaskets that are bad so i need to replace them with copper ones. Where can i get these?
Also any tricks to try and find my leak besides using sea foam? Thanks

A stethoscope with a piece of steel brake line in the rubber tube will help pinpoint many eluding sounds.
