Correct on both counts. The way TDI originally preserved the DOC was by using the factory DOC/DPF-equipped down pipe, but removing the DPF portion.
Another option that has been mentioned in a few other threads to help with the exhaust odor is to simply install some high flow converters further downstream on the exhaust. iaknown said this had a notable improvement over being completely catless/DOCless.
