Exhaust manifold to pipe leaking

I did the head gasket in January. Ever since I put it back together the exhaust is leaking out between the exhaust manifold and pipe. I believe this is causing a "false" lean code to be thrown. Has anyone experienced this problem? What is the remedy? I am quite disappointed I had to do a head gasket a little under 100,000. I feel there is a lack of quality in this car. I apologize for me venting, I really do like the car, just frustrated with all my car problems recently. All and any input is greatly appreciated. Thanks.

replace the gasket in the exhaust between the pipe and the manifold! then take it to autozone and have them clear the engine code...

now for the head gasket deal... it doesnt matter how many miles are on a car for the head gasket to go! its basically how the car was treated... like do you beat on it, did the owner before you beat on it, was it kept in perfect condition, were all maintenance and check ups completed, do you change the oil atleast every 3000 miles, are the fluids all at the right levels, have you ever overheated the car............ thoses are all things that can cause anything to go wrong with the car!! dont be upset/disappointed with the car, be upset with how the car was treated!

I have already replaced the gasket three times. And yes, I did have the code cleared many times. Apparently the mating surfaces have become warped. Any other thoughts would be greatly appreciated, or I am going to JB weld the sucker, ha. Actually, I might have to see if I can get the manifold surface machined. Thanks.

get a new pipe or manifold is the only other option... why not upgrade now and get a header and exhaust or something!

are you torqueing it tight enough? if the other option is a new header/exhaust you might as well pound the shit out of it with an impact wrench first to see if it works
