Pacesetter long tube headers on my 2002 silverado, i live in Saskatchewan Canada. They were put on last spring, I tried to paint them with high temperature heat paint, and that was a joke, that paint didn't do jack ****. But underneath the paint there was pacesetters black primer, and it's still held on there for a year. The gaskets they give you are garbage, get thick soft aluminum gaskets, i can't remember what ones i got but they're 1/4" thick, and compress down to 1/8 inch, and form to any warped headers or manifolds. They expand faster with heat then the headers, so they make an unbelievable seal.
