Getting ready to put my Lethal O/R h-pipes on and wondered if it would be a good idea to spray the old manifold gaskets with the copper spray to help prevent leaks. Anybody use this stuff when they changed out their pipes?
Shop who installed mine put some orange permatex on the exhaust flanges. I have zero leaks. I hear it's not a must but there are some other guys in here who have done the same. If you got it on hand I say go for it.
