ok i installed headers today all went ok intill i noticed that i have 2 porblems one is the pipes have a hard time connecting to the headers seems a little short which doesnt close the gap 100% so it has about 1/2 an inch opening which isnt good but the other side my bolt striped so i have only one side clamped on about 1/2 on the other pipe also its connected to an h pipe. i live in sacramento california and i ask this because i was going to take for smog tomarrow and someone said if i have leaks it will help pass a lot easer. but im thinking this will cause my car not to pass anyone have any ideas or know anything about this? or my problem?
