Stock exhaust manifold

[Trapper]

Hey is anyone using their stock exhaust manifold and can it support twins?

:badidea: I went through the same bull**** with my setup. It is better to just spend the money and get the after market one.

The stock one can warp and crack and cause bolts to break. When you flip the manifold and bolt it on it may crack. about 50% of the stock manifolds that do this surive but the other 50% do not.

That is what every company i talked to told me. The stock are already junk so i would not reuse it if it were me.

A friend of mine is making 600HP+ with a 12v running a s300 s400 twin stack building 85 psi and he is still running the stock manifold.
