mismatched non seqeuntial turbo?

33 psi, now that's a well built system. Hard to tell but it looks like it's done the same way, except it appears to be sequential and just a tad bigger, the cold side looks like a 4" header, gives me a headache trying to figure out where all the pipes go. interested in the waste-gate connection, is it internal on one and actuated by the other?
