From the pictures I found while searching, I could only find 1 bracket that goes to the downpipe, is that really the only one? I see some bolt holes toward the passenger side too, is there 2 brackets or 1?

 

IIRC there are three brackets. There is one from the transmission side engine block to the turbo compressor cover. There is one installed at the back of the engine block which is the main support bracket. There is one bracket at the o2 housing and back of the engine block.

 

Thanks that helps, I think I found the 3. In the link below, it is number 3 and 4 and then an additional bracket on the o2 bracket (not listed). Does that look right?

3, 4, and 7.
This is the bracket at the o2 housing and back of the engine block underneath the exhaust manifold.
