    my buddy cracked his on his 95 and my dad just put a small spot weld (hole was dime size) on it (sorry dont know specs of the weld) and about 3-4 weeks later the manifold split a 4" crack in a different spot, it may just be better to go ahead and get a new one,

    Typically it is not recommend to weld on the stock exhaust manifolds. They are cast and when you weld on them, you typically can not get your weld hot enough, so the weld is not going to bold correctly.

    Your best bet (and lest amount trouble in the long run) would be to get either a replacment manifold or buy an aftermarket header.
