BTW there is nothing "fancy" about that manifold becuase a T04 Garret blah blah blah is a STOCK TURBO.
I see that it says something about tuning on it, but it was cracked and cast welds are hit or miss...if the person knew what they were doing or not.
If it cracked once who is to say it won't crack again?
Honestly, with so little complaint about the stock manifolds and their resistance to cracking, I wouldn't fork out the cash for this thing.
IF you want something special...build a header
