btw, for reference, their are Long scratch marks on part of the header, and than u see the tiny hole, thats how i kno it happened cuz my dumb friend jumped the curb. my friend filled it with some sealent, he said dont worry, wont get into cat, it will just burn off, temporary fix, he said watch, in a couple of hrs, it will be gone even LOL, sealent is not good enuff for the extreme heat. anyway, btw, my car has been maintained well, did coolant flush recently, fuel injector cleaned in both fuel tank and put that crap in the carberator part inside the hood, and changed plugs to denso iridiums(nice) recently. car runs AMAZING except for the occasionally fallin apart feeling when the check engine light comes on LOL, i cant accelerate past 50 without hittin accelerator a bit harder than normal.
