What's the best way to pressure test some CMI E-Tops?

Young Performance

Stand the header up like it would be on the engine. Hook up a garden hose to the water inlet distribution tube. Fill the header up with water all the way to the top and turn off the water. Then plug off the water outlet fitting at the collector. Turn on the hose and hope for the best. At this point you can lay the header down or move it around to see if it leaks. Hope this helps, Eddie.
