Up-pipe is from the engine up to the turbo.
Downpipe is from the turbo to your exhaust system.
Most people replace the downpipe with an item that doesnt have a cat. You should then consider some form of remap / boost control to get the fueling and boost set correctly so as not to damage the engine.
