Turbo 440 duster

Very impressive. I'm a little confused about the plumbing, tho. Looks like most everything turbo-wise sits on the driver side and you mention using a stock TTI on the pass side. But I see alot of non-stock/non-TTI plumbing running on the pass side. Can you explain the flow a little more? Is the wastegate/turbine outlet routed under the front of the engine and back over to the pass side somehow?
