Ok guys, since installing my Zard header, I've found all manner of exhaust leaks. WTF do I need to do to seal this thing up and what is the step-by-step process? I've tried Ultra-Black Permatex and that helped a bit, but do I need to just keep reapplying the crap until it seals it completely? There has to be a sure-fire way to do this that is simple and effective (putting the stock header back on is not an option). I already know I have a few spring clips that need to be replaced with shorter ones.
