I would not go with option A. Most exhaust manifolds are cast iron (I don't see any reason our's wouldn't be as well but I'm not sure). Cast Iron doesn't weld very well and will really only stem the problem until other cracks develop from the difference in heat stress. I'd get a new manifold (stock, or aftermarket).tazracing said:I was just informed that my front exhaust manifold is cracked. I am running 13G turbos, so should I:
a. Just get the crack welded
b. get a set of aftermarket exhaust headers
if b who makes them and appox how much?
