I have a exhaust leak on one of the pipes where the header and side pipe slid together. Last fall I took it to a shop where we cut the the side pipe where it slides on to the header and pulled it together and welded it. It still leaks and I tryed to separate the header from the side pipe but they are welded together.
Looking for a suggestion to fix; I can JB Weld the joint shut or cut the pipe to separate it and repair it....thoughts??
