The reason why cast turbo exhaust manifolds are recommended is because they will outlast almost any tube turbo exhaust manifolds.
If you're going to argue stainless steel tube turbo exhaust manifolds, then cast units will almost always be cheaper.
Except for all that Made-in-China crap...
There's an underlying problem with buying all that cheap ass Made-in-China crap...
Economies.
People bitch about how the US dollar is devalued and how China's economy is pumping like there's no tomorrow.
Gee...I wonder why...duh.
You wanna save your dollars now and bend the U.S. economy over, go buy all that cheap crap.
Sorry for the global economy rant.
