You know I did go to a one man shop to have it fixed, The first thing he did was replace the two flange pipes and mate them to the header surface. He used a flat gasket on both sides and now there is no leak, they must have bent something way out of place. I now have total quiet and 4 speed smothness, I don't know what happened, I nust have replaced the dounut gasket 4 times with no suscess. live and learn!
