Those headers are nice but are tight against everything around them I've often wondered how some components survive...You've only got so many choices using them...Heat shield, header wrap/coating,solid or rubber mounts, and the carb tune as some have suggested...
Take your pic or combine them any way you like...
I think I'm going to have to go with the Chinese menu approach - all of the above.
I talked to a rep at Mancini about that mount and they didn't think it would hold up to the heat. They suggested a wrap.
Since this is a daily driver car and the engine is a little shaky I think it's best I stay away from a solid mount. I'm going to have to go with a wrap and heat shield if possible.
My last resort is to uninstall the headers and go with manifolds.
