I wonder if anyone else on here installed a set of Mickey Thompson Super Scavenger Headers back in the day? Now "that" was fun, actually easier than you might imagine. That design was way ahead of its time. 2" tubular steel headers to a 3-1/2" collector. I don't recall having any issues installing in my '67 Chevelle SS other than loosening a motor mount and slightly jacking up the engine. When I think about it, those tubes were easy to maneuver because they went into the long collectors at different lengths, the equal tubing wasn't all scrunched up beside the engine on each side before the collector, making the install a heck of a lot easier. Again, why don't any header manufacturers do this these days? Dumb if you ask me! But, what do I know?
