I have a 3 piece coated header y-pipe and it leaks at the seams, therefore I want to weld it up solid and be done with it.
What do I need to do to ensure the weld holds up cause I was told that you cant just weld over coating. Maybe I was told wrong. I have already gone around the seams with a wire grinder with wire brush but I still dont think I have hit bare metal. If I need to I guess I can use a stone or a wheel to just break the surface.
I will be painting the welded areas with POR-15 high temp so I am not worried about the coating around the seams.
I just need to get a heads up before I take it to the muffler shop. I am also open to other suggestions to seal the seams.
Thanks
